 For navbars that never collapse, add the `.navbar-expand` class on the navbar. For navbars that always collapse, don’t add any `.navbar-expand` class.

+title: Checkbox
+description: Highly customizable, native checkbox `<input>` elements for presenting toggleable options.
+toc: true
+---
+
+**Trialing new components with the following rules:**
+
+- New components are purely components, they don't assume layout of any kind.
+- New options for form layout:
+  - Use new form groups to lay out your forms: `.control-group`, `.check-group`, `.radio-group`.
+  - Use helpers to lay out your forms—`.hstack` and `.vstack`—with utilities.
+
+## Basic checkbox
+
+All checkbox styling is contained to a wrapper class, `.check`. This does the following:
+
+- Adds a stacking grid layout for the checkbox and custom SVG icon.
+- Overrides the default `<input>` appearance with themed colors.
+- Handles the toggling of separate paths in our custom SVG for the `:checked` and indeterminate states. Two `<path>`s are included in the SVG, one for each state, and the appropriate `<path>` is shown based on the `<input>`’s state.
+
+For folks looking to replace our provided icons, you'll need to add the `.checked` and `.indeterminate` classes to the `<path>`s and use them in a single `<svg>` element.
+
+Checkbox layout and labels are handled with additional HTML and CSS.
+
+<Example code={`<div class="check">
+    <input type="checkbox" id="check" checked />
+    <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 20 20'>
+      <path class="checked" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='m6 10 3 3 6-6'/>
+      <path class="indeterminate" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='M6 10h8'/>
+    </svg>
+  </div>`} />
+
+## Indeterminate
+
+Checkboxes can utilize the indeterminate pseudo class when manually set via JavaScript. There is no available HTML attribute for specifying it.
+
+<Example addStackblitzJs class="bd-example-indeterminate" code={`<div class="check">
+    <input type="checkbox" id="checkIndeterminate" />
+    <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 20 20'>
+      <path class="checked" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='m6 10 3 3 6-6'/>
+      <path class="indeterminate" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='M6 10h8'/>
+    </svg>
+  </div>`} />
+
+## Label
+
+Wrap the `.check` in a `<b-checkgroup>` layout component and add your label. We use a custom element for layout here that sets some basic flexbox styling.
+
+Consider margin utilities for additional spacing, and flex utilities for alignment.
+
+<Example code={`<b-checkgroup>
+    <div class="check">
+      <input type="checkbox" id="checkLabel" />
+      <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 20 20'>
+        <path class="checked" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='m6 10 3 3 6-6'/>
+        <path class="indeterminate" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='M6 10h8'/>
+      </svg>
+    </div>
+    <label for="checkLabel">Example new checkbox</label>
+  </b-checkgroup>`} />
+
+## Description
+
+With this layout approach, you can easily add a description or other content after the label. Here we use another custom element, `<b-vstack>`, to stack the label and description.
+
+<Example code={`<b-checkgroup>
+    <div class="check">
+      <input type="checkbox" id="checkDescription" />
+      <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 20 20'>
+        <path class="checked" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='m6 10 3 3 6-6'/>
+        <path class="indeterminate" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='M6 10h8'/>
+      </svg>
+    </div>
+    <b-vstack>
+      <label for="checkDescription">Example new checkbox</label>
+      <small class="description">Supporting description for the above label.</small>
+    </b-vstack>
+  </b-checkgroup>`} />
+
+## Disabled
+
+Add the `disabled` attribute and the associated `<label>`s are automatically styled to match with a lighter color to help indicate the input’s state.
+
+<Example code={`<b-checkgroup>
+    <div class="check">
+      <input type="checkbox" id="checkDisabled" disabled />
+      <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 20 20'>
+        <path class="checked" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='m6 10 3 3 6-6'/>
+        <path class="indeterminate" fill='none' stroke='currentcolor' stroke-linecap='round' stroke-linejoin='round' stroke-width='3' d='M6 10h8'/>
+      </svg>
+    </div>
+    <label for="checkDisabled">Example new checkbox</label>
+  </b-checkgroup>`} />
+
+<Example code={`<b-checkgroup>
+    <div class="check">
+      <input type="checkbox" id="checkDisabledChecked" checked disabled />

+    <label for="checkDisabledChecked">Example new checkbox</label>
+  </b-checkgroup>`} />

-title: Checks and radios
-description: Create consistent cross-browser and cross-device checkboxes and radios with our completely rewritten checks component.
-aliases: "/docs/[[config:docs_version]]/forms/checks/"
-toc: true
----
-
-## Approach
-
-Browser default checkboxes and radios are replaced with the help of `.form-check`, a series of classes for both input types that improves the layout and behavior of their HTML elements, that provide greater customization and cross browser consistency. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
-
-Structurally, our `<input>`s and `<label>`s are sibling elements as opposed to an `<input>` within a `<label>`. This is slightly more verbose as you must specify `id` and `for` attributes to relate the `<input>` and `<label>`. We use the sibling selector (`~`) for all our `<input>` states, like `:checked` or `:disabled`. When combined with the `.form-check-label` class, we can easily style the text for each item based on the `<input>`’s state.
-
-Our checks use custom Bootstrap icons to indicate checked or indeterminate states.
-
-## Checks
-
-<Example code={`<div class="form-check">
-    <input class="form-check-input" type="checkbox" value="" id="checkDefault">
-    <label class="form-check-label" for="checkDefault">
-      Default checkbox
-    </label>
-  </div>
-  <div class="form-check">
-    <input class="form-check-input" type="checkbox" value="" id="checkChecked" checked>
-    <label class="form-check-label" for="checkChecked">
-      Checked checkbox
-    </label>
-  </div>`} />
-
-### Indeterminate
-
-Checkboxes can utilize the `:indeterminate` pseudo class when manually set via JavaScript (there is no available HTML attribute for specifying it).
-
-<Example addStackblitzJs class="bd-example-indeterminate" code={`<div class="form-check">
-    <input class="form-check-input" type="checkbox" value="" id="checkIndeterminate">
-    <label class="form-check-label" for="checkIndeterminate">

-    </label>
-  </div>`} />
-
-### Disabled
-
-Add the `disabled` attribute and the associated `<label>`s are automatically styled to match with a lighter color to help indicate the input’s state.
-
-<Example addStackblitzJs class="bd-example-indeterminate" code={`<div class="form-check">

-## Radios
-
-<Example code={`<div class="form-check">
-    <input class="form-check-input" type="radio" name="radioDefault" id="radioDefault1">
-    <label class="form-check-label" for="radioDefault1">

-    </label>

-    </label>
-  </div>`} />
-
-### Disabled
-

-
-<Example code={`<div class="form-check">
-    <input class="form-check-input" type="radio" name="radioDisabled" id="radioDisabled" disabled>

-    <label class="form-check-label" for="radioCheckedDisabled">
-      Disabled checked radio
-    </label>
-  </div>`} />
-
-## Switches
-
-A switch has the markup of a custom checkbox but uses the `.form-switch` class to render a toggle switch. Consider using `role="switch"` to more accurately convey the nature of the control to assistive technologies that support this role. In older assistive technologies, it will simply be announced as a regular checkbox as a fallback. Switches also support the `disabled` attribute.
-
-<Example code={`<div class="form-check form-switch">
-    <input class="form-check-input" type="checkbox" role="switch" id="switchCheckDefault">
-    <label class="form-check-label" for="switchCheckDefault">Default switch checkbox input</label>
-  </div>
-  <div class="form-check form-switch">
-    <input class="form-check-input" type="checkbox" role="switch" id="switchCheckChecked" checked>
-    <label class="form-check-label" for="switchCheckChecked">Checked switch checkbox input</label>
-  </div>
-  <div class="form-check form-switch">
-    <input class="form-check-input" type="checkbox" role="switch" id="switchCheckDisabled" disabled>
-    <label class="form-check-label" for="switchCheckDisabled">Disabled switch checkbox input</label>
-  </div>
-  <div class="form-check form-switch">
-    <input class="form-check-input" type="checkbox" role="switch" id="switchCheckCheckedDisabled" checked disabled>
-    <label class="form-check-label" for="switchCheckCheckedDisabled">Disabled checked switch checkbox input</label>
-  </div>`} />
-
-### Native switches
-
-Progressively enhance your switches for mobile Safari (iOS 17.4+) by adding a `switch` attribute to your input to enable haptic feedback when toggling switches, just like native iOS switches. There are no style changes attached to using this attribute in Bootstrap as all our switches use custom styles.
-
-<Example code={`<div class="form-check form-switch">
-    <input class="form-check-input" type="checkbox" value="" id="checkNativeSwitch" switch>
-    <label class="form-check-label" for="checkNativeSwitch">
-      Native switch haptics
-    </label>
-  </div>`} />
-
-Be sure to read more about [the switch attribute on the WebKit blog](https://webkit.org/blog/15054/an-html-switch-control/). Safari 17.4+ on macOS and iOS both have native-style switches in HTML while other browsers simply fall back to the standard checkbox appearance. Applying the attribute to a non-Bootstrap checkbox in more recent versions of Safari will render a native switch.
-
-## Default (stacked)
-
-By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with `.form-check`.
-
-<Example code={`<div class="form-check">
-    <input class="form-check-input" type="checkbox" value="" id="defaultCheck1">
-    <label class="form-check-label" for="defaultCheck1">
-      Default checkbox
-    </label>
-  </div>
-  <div class="form-check">
-    <input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled>
-    <label class="form-check-label" for="defaultCheck2">
-      Disabled checkbox
-    </label>
-  </div>`} />
-
-<Example code={`<div class="form-check">
-    <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked>
-    <label class="form-check-label" for="exampleRadios1">
-      Default radio
-    </label>
-  </div>
-  <div class="form-check">
-    <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2">
-    <label class="form-check-label" for="exampleRadios2">
-      Second default radio
-    </label>
-  </div>
-  <div class="form-check">
-    <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled>
-    <label class="form-check-label" for="exampleRadios3">
-      Disabled radio
-    </label>
-  </div>`} />
-
-## Inline
-
-Group checkboxes or radios on the same horizontal row by adding `.form-check-inline` to any `.form-check`.
-
-<Example code={`<div class="form-check form-check-inline">
-    <input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1">
-    <label class="form-check-label" for="inlineCheckbox1">1</label>
-  </div>
-  <div class="form-check form-check-inline">
-    <input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2">
-    <label class="form-check-label" for="inlineCheckbox2">2</label>
-  </div>
-  <div class="form-check form-check-inline">
-    <input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled>
-    <label class="form-check-label" for="inlineCheckbox3">3 (disabled)</label>
-  </div>`} />
-
-<Example code={`<div class="form-check form-check-inline">
-    <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
-    <label class="form-check-label" for="inlineRadio1">1</label>
-  </div>
-  <div class="form-check form-check-inline">
-    <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
-    <label class="form-check-label" for="inlineRadio2">2</label>
-  </div>
-  <div class="form-check form-check-inline">
-    <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3" disabled>
-    <label class="form-check-label" for="inlineRadio3">3 (disabled)</label>
-  </div>`} />
-
-## Reverse
-
-Put your checkboxes, radios, and switches on the opposite side with the `.form-check-reverse` modifier class.
-
-<Example code={`<div class="form-check form-check-reverse">
-    <input class="form-check-input" type="checkbox" value="" id="reverseCheck1">
-    <label class="form-check-label" for="reverseCheck1">
-      Reverse checkbox
-    </label>
-  </div>
-  <div class="form-check form-check-reverse">
-    <input class="form-check-input" type="checkbox" value="" id="reverseCheck2" disabled>
-    <label class="form-check-label" for="reverseCheck2">
-      Disabled reverse checkbox
-    </label>
-  </div>
-
-  <div class="form-check form-switch form-check-reverse">
-    <input class="form-check-input" type="checkbox" id="switchCheckReverse">
-    <label class="form-check-label" for="switchCheckReverse">Reverse switch checkbox input</label>
-  </div>`} />
-
-## Without labels
-
-Omit the wrapping `.form-check` for checkboxes and radios that have no label text. Remember to still provide some form of accessible name for assistive technologies (for instance, using `aria-label`). See the [forms overview accessibility]([[docsref:/forms/overview/#accessibility]]) section for details.
-
-<Example code={`<div>
-    <input class="form-check-input" type="checkbox" id="checkboxNoLabel" value="" aria-label="...">
-  </div>
-
-  <div>
-    <input class="form-check-input" type="radio" name="radioNoLabel" id="radioNoLabel1" value="" aria-label="...">
-  </div>`} />
-
-## Toggle buttons
-
-Create button-like checkboxes and radio buttons by using `.btn` styles rather than `.form-check-label` on the `<label>` elements. These toggle buttons can further be grouped in a [button group]([[docsref:/components/button-group]]) if needed.
-
-### Checkbox toggle buttons
-
-<Example code={`<input type="checkbox" class="btn-check" id="btn-check" autocomplete="off">
-<label class="btn btn-primary" for="btn-check">Single toggle</label>
-
-<input type="checkbox" class="btn-check" id="btn-check-2" checked autocomplete="off">
-<label class="btn btn-primary" for="btn-check-2">Checked</label>
-
-<input type="checkbox" class="btn-check" id="btn-check-3" autocomplete="off" disabled>
-<label class="btn btn-primary" for="btn-check-3">Disabled</label>`} />
-
-<Example code={`<input type="checkbox" class="btn-check" id="btn-check-4" autocomplete="off">
-<label class="btn" for="btn-check-4">Single toggle</label>

-
-<input type="checkbox" class="btn-check" id="btn-check-6" autocomplete="off" disabled>
-<label class="btn" for="btn-check-6">Disabled</label>`} />
-
-<Callout>
-Visually, these checkbox toggle buttons are identical to the [button plugin toggle buttons]([[docsref:/components/buttons#button-plugin]]). However, they are conveyed differently by assistive technologies: the checkbox toggles will be announced by screen readers as “checked“/“not checked“ (since, despite their appearance, they are fundamentally still checkboxes), whereas the button plugin toggle buttons will be announced as “button“/“button pressed“. The choice between these two approaches will depend on the type of toggle you are creating, and whether or not the toggle will make sense to users when announced as a checkbox or as an actual button.

+
+## Basic radio
+
+Similar to checkboxes, radios are styled with the `.radio` class. However, there's no custom SVG as we use a Unicode character for the checked state.
+
+<Example code={`<input type="radio" id="radio" class="radio" />`} />
+
+## Label
+
+Wrap the `.radio` in a `<b-radiogroup>` layout component and add your label. We use a custom element for layout here that sets some basic flexbox styling.
+
+<Example code={`<b-radiogroup>
+    <input type="radio" id="radioLabel" class="radio" />
+    <label for="radioLabel">Example new radio</label>
+  </b-radiogroup>
+  `} />
+
+## Description
+
+With this layout approach, you can easily add a description or other content after the label. Here we use another custom element, `<b-vstack>`, to stack the label and description.
+
+<Example code={`<b-radiogroup>
+    <input type="radio" id="radioLabelDescription" class="radio" />
+    <b-vstack>
+      <label for="radioLabelDescription">Example new radio</label>
+      <small class="description">Supporting description for the above label.</small>
+    </b-vstack>
+  </b-radiogroup>
+  `} />
+
+## Disabled
+
+Add the `disabled` attribute and the associated `<label>`s are automatically styled to match with a lighter color to help indicate the input’s state.
+
+<Example code={`<b-radiogroup>
+    <input type="radio" id="radioDisabled" class="radio" disabled />
+    <label for="radioDisabled">Example new radio</label>

+title: Switch
+description: Custom toggle component built on top of native `<input>` checkbox elements.
+toc: true
+---
+
+## Basic switch
+
+Switches are built with checkboxes under the hood, so their HTML closely mirrors that of checkboxes, including optional layout components.
+
+Switches work by layering an invisible checkbox over the custom switch indicator. This preserves interactivity while giving you a completely customizable layer underneath.
+
+Switches also include the `switch` attribute for browsers that support it. This provides haptic feedback when toggling the switch.
+
+<Example code={`<div class="switch">
+    <input type="checkbox" value="" id="switch" switch>
+  </div>`} />
+
+## Label
+
+Wrap the `.switch` in a `<b-checkgroup>` layout component and add your label. We use a custom element for layout here that sets some basic flexbox styling. Switches are checkboxes under the hood, so we reused the same custom element here.
+
+Consider margin utilities for additional spacing, and flex utilities for alignment, especially when using small or large switches.
+
+<Example class="d-flex flex-column gap-3" code={`<b-checkgroup>
+    <div class="switch switch-sm mt-1">
+      <input type="checkbox" value="" id="switchSmLabel" switch>
+    </div>
+    <label for="switchSmLabel">Small switch</label>
+  </b-checkgroup>
+
+  <b-checkgroup>
+    <div class="switch">
+      <input type="checkbox" value="" id="switchMdLabel" switch>
+    </div>
+    <label for="switchMdLabel">Default switch</label>
+  </b-checkgroup>`} />
+
+## Disabled
+
+Add the `disabled` attribute and the associated `<label>`s are automatically styled to match with a lighter color to help indicate the input’s state.
+
+<Example class="d-flex flex-column gap-3" code={`<b-checkgroup>
+    <div class="switch">
+      <input type="checkbox" value="" id="switchDisabledLabel" switch disabled>
+    </div>
+    <label for="switchDisabledLabel">Disabled switch</label>
+  </b-checkgroup>`} />
+
+## Sizes
+
+Add a size modifier class to make your switch appear smaller or larger.
+
+<Example class="d-flex flex-column gap-3" code={`<div class="switch switch-sm">
+    <input type="checkbox" value="" id="switchSizeSm" switch>
+  </div>

-## v5.3.6
+## v6.0.0 Migration
 
-### Dependencies
+Bootstrap 6 is a major release with many breaking changes to modernize our codebase, adopt newer build tools, and improve customization. Keep reading for a guide on how to migrate from v5 to v6, and a full changelog of what's new.
 
-- Migrated from Hugo to Astro for building our documentation
+1. Bump your Bootstrap dependency:
 
-## v5.3.0
+   ```json
+   {
+     "dependencies": {
+       "bootstrap": "^6.0.0"
+     }
+   }
+   ```
 
-If you’re migrating from our previous alpha releases of v5.3.0, please review their changes in addition to this section.
+2. If using all of Bootstrap's Sass files, include it in your Sass using `@use`:
 
-### Helpers
+   ```scss
+   @use "bootstrap/scss/bootstrap";
+   ```
 
-- [Colored links]([[docsref:/helpers/colored-links]]) once again have `!important` so they work better with our newly added link utilities.
+   With this, you can then easily override Bootstrap's Sass variables and maps:
 
-### Utilities
+   ```scss
+   @use "bootstrap/scss/bootstrap" with (
+    $spacer: 1rem,
+    $enable-reduced-motion: true,
+   );
+   ```
 
-- Added new `.d-inline-grid` [display utility]([[docsref:/utilities/display]]).
+3. If using only certain parts of Bootstrap's Sass files, you can use `@use` to import them individually. Be aware that our Sass file structure has changed and you may need to adjust your imports accordingly.
 
-## v5.3.0-alpha2
+   ```scss
+   @use "bootstrap/scss/forms";
+   ```
 
-If you’re migrating from our previous alpha release of v5.3.0, please review the changes listed below.
+4. Update HTML and CSS per the changelog and updates in the documentation.
 
-### CSS variables
+5. Recompile your Sass to see the changes.
 
-- Removed several duplicate and unused root CSS variables.
+## v6.0.0 Changelog
 
-### Color modes
+### CSS
 
-- Dark mode colors are now derived from our theme colors (e.g., `$primary`) in Sass, rather than color specific tints or shades (e.g., `$blue-300`). This allows for a more automated dark mode when customizing the default theme colors.
-
-- Added Sass maps for generating theme colors for dark mode text, subtle background, and subtle border.
-
-- [Snippet examples]([[docsref:/examples/#snippets]]) are now ready for dark mode with updated markup and reduced custom styles.
-
-- Added `color-scheme: dark` to dark mode CSS to change OS level controls like scrollbars
-
-- Form validation `border-color` and text `color` states now respond to dark mode, thanks to new Sass and CSS variables.
-
-- Dropped recently added form control background CSS variables and reassigned the Sass variables to use CSS variables instead. This simplifies the styling across color modes and avoids an issue where form controls in dark mode wouldn’t update properly.
-
-- Our `box-shadow`s will once again always stay dark instead of inverting to white when in dark mode.
-
-- Improved HTML and JavaScript for our color mode toggle script. The selector for changing the active SVG has been improved, and the markup made more accessible with ARIA attributes.
-
-- Improved docs code syntax colors and more across light and dark modes.
-
-### Typography
-
-- We no longer set a color for `$headings-color-dark` or `--bs-heading-color` for dark mode. To avoid several problems of headings within components appearing the wrong color, we’ve set the Sass variable to `null` and added a `null` check like we use on the default light mode.
-
-### Components
-
-- Cards now have a `color` set on them to improve rendering across color modes.
-
-- Added new `.nav-underline` variant for our navigation with a simpler bottom border under the active nav link. [See the docs for an example.]([[docsref:/components/navs-tabs#underline]])
-
-- Navs now have new `:focus-visible` styles that better match our custom button focus styles.
-
-### Helpers
-
-- Added new `.icon-link` helper to quickly place and align Bootstrap Icons alongside a textual link. Icon links support our new link utilities, too.
-
-- Added new focus ring helper for removing the default `outline` and setting a custom `box-shadow` focus ring.
-
-### Utilities
-
-- Renamed Sass and CSS variables `${color}-text` to `${color}-text-emphasis` to match their associated utilities.
-
-- Added new `.link-body-emphasis` helper alongside our [colored links]([[docsref:/helpers/colored-links]]). This creates a colored link using our color mode responsive emphasis color.
-
-- Added new link utilities for link color opacity, underline offset, underline color, and underline opacity. [Explore the new links utilities.]([[docsref:/utilities/link]])
-
-- CSS variable based `border-width` utilities have been reverted to set their property directly (as was done prior to v5.2.0). This avoids inheritance issues across nested elements, including tables.
-
-- Added new `.border-black` utility to match our `.text-black` and `.bg-black` utilities.
-
-- <span class="badge text-warning-emphasis bg-warning-subtle">Deprecated</span> The `.text-muted` utility and `$text-muted` Sass variable have been deprecated and replaced with `.text-body-secondary` and `$body-secondary-color`.
-
-### Docs
-
-- Examples are now displayed with the appropriate light or dark color mode as dictated by the setting in our docs. Each example has an individual color mode picker.
-
-- Improved included JavaScript for live Toast demo.
-
-- Added `twbs/examples` repo contents to the top of the Examples page.
-
-### Tooling
-
-- Added SCSS testing via True to help test our utilities API and other customizations.
-
-- Replaced instances of our bootstrap-npm-starter project with the newer and more complete [twbs/examples repo](https://github.com/twbs/examples).

-
-- **Global support for light (default) and dark color modes.** Set color mode globally on the `:root` element, on groups of elements and components with a wrapper class, or directly on components, with `data-bs-theme="light|dark"`. Also included is a new `color-mode()` mixin that can output a ruleset with the `data-bs-theme` selector or a media query, depending on your preference.
-
-  <span class="badge text-warning-emphasis bg-warning-subtle">Deprecated</span> Color modes replace dark variants for components, so  `.btn-close-white`, `.carousel-dark`, `.dropdown-menu-dark`, and `.navbar-dark` are deprecated.
-
-- **New extended color system.** We’ve added new theme colors (but not in `$theme-colors`) for a more nuanced, system-wide color palette with new secondary, tertiary, and emphasis colors for `color` and `background-color`. These new colors are available as Sass variables, CSS variables, and utilities.
-
-- We’ve also expanded our theme color Sass variables, CSS variables, and utilities to include text emphasis, subtle background colors, and subtle border colors. These are available as Sass variables, CSS variables, and utilities.
-
-- Adds new `_variables-dark.scss` stylesheet to house dark-mode specific overrides. This stylesheet should be imported immediately after the existing `_variables.scss` file in your import stack.

-### CSS variables
-
-- Restores CSS variables for breakpoints, though we don’t use them in our media queries as they’re not supported. However, these can be useful in JS-specific contexts.
-
-- Per the color modes update, we’ve added new utilities for new Sass CSS variables `secondary` and `tertiary` text and background colors, plus `{color}-bg-subtle`, `{color}-border-subtle`, and `{color}-text-emphasis` for our theme colors. These new colors are available through Sass and CSS variables (but not our color maps) with the express goal of making it easier to customize across multiple colors modes like light and dark.
-
-- Adds additional variables for alerts, `.btn-close`, and `.offcanvas`.
-
-- The `--bs-heading-color` variable is back with an update and dark mode support. First, we now check for a `null` value on the associated Sass variable, `$headings-color`, before trying to output the CSS variable, so by default it’s not present in our compiled CSS. Second, we use the CSS variable with a fallback value, `inherit`, allowing the original behavior to persist, but also allowing for overrides.
-
-- Converts links to use CSS variables for styling `color`, but not `text-decoration`. Colors are now set with `--bs-link-color-rgb` and `--bs-link-opacity` as `rgba()` color, allowing you to customize the translucency with ease. The `a:hover` pseudo-class now overrides `--bs-link-color-rgb` instead of explicitly setting the `color` property.
-
-- `--bs-border-width` is now being used in more components for greater control over default global styling.
-
-- Adds new root CSS variables for our `box-shadow`s, including `--bs-box-shadow`, `--bs-box-shadow-sm`, `--bs-box-shadow-lg`, and `--bs-box-shadow-inset`.

-
-### Progress bars
-
-The markup for [progress bars]([[docsref:/components/progress]]) has been updated in v5.3.0. Due to the placement of `role` and various `aria-` attributes on the inner `.progress-bar` element, **some screen readers were not announcing zero value progress bars**. Now, `role="progressbar"` and the relevant `aria-*` attributes are on the outer `.progress` element, leaving the `.progress-bar` purely for the visual presentation of the bar and optional label.
-
-While we recommend adopting the new markup for improved compatibility with all screen readers, note that the legacy progress bar structure will continue to work as before.
-
-```html
-<!-- Previous markup -->
-<div class="progress">
-  <div class="progress-bar" role="progressbar" aria-label="Basic example" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
-</div>
-

-  <div class="progress-bar" style="width: 25%"></div>
-</div>
-```
-
-We’ve also introduced a new `.progress-stacked` class to more logically wrap [multiple progress bars]([[docsref:/components/progress#multiple-bars]]) into a single stacked progress bar.
-
-```html
-<!-- Previous markup -->
-<div class="progress">
-  <div class="progress-bar" role="progressbar" aria-label="Segment one" style="width: 15%" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100"></div>

-### Forms
-
-- `.form-control` is now styled with CSS variables to support color modes. This includes the addition of two new root CSS variables for the default and disabled form control backgrounds.
-
-- `.form-check` and `.form-switch` components are now built with CSS variables for setting the `background-image`. The usage here differs from other components in that the various focus, active, etc states for each component aren’t set on the base class. Instead, the states override one variable (e.g., `--bs-form-switch-bg`).
-
-- Floating form labels now have a `background-color` to fix support for `<textarea>` elements. Additional changes have been made to also support disabled states and more.
-
-- Fixed display of date and time inputs in WebKit based browsers.
-
-### Utilities
-
-- <span class="badge text-warning-emphasis bg-warning-subtle">Deprecated</span> `.text-muted` will be replaced by `.text-body-secondary` in v6.
-
-  With the addition of the expanded theme colors and variables, the `.text-muted` variables and utility have been deprecated with v5.3.0. Its default value has also been reassigned to the new `--bs-secondary-color` CSS variable to better support color modes. It will be removed in v6.0.0.
-
-- Adds new `.overflow-x`, `.overflow-y`, and several `.object-fit-*` utilities. _The object-fit property is used to specify how an `<img>` or `<video>` should be resized to fit its container, giving us a responsive alternative to using `background-image` for a resizable fill/fit image._
-
-- Adds new `.fw-medium` utility.
-
-- Added new [`.z-*` utilities]([[docsref:/utilities/z-index]]) for `z-index`.
-
-- [Box shadow utilities]([[docsref:/utilities/shadows]]) (and Sass variables) have been updated for dark mode. They now use `--bs-body-color-rgb` to generate the `rgba()` color values, allowing them to easily adapt to color modes based on the specified foreground color.

-## v5.2.0
-
-<hr class="mb-4"/>
-
-### Refreshed design
-
-Bootstrap v5.2.0 features a subtle design update for a handful of components and properties across the project, **most notably through refined `border-radius` values on buttons and form controls**. Our documentation also has been updated with a new homepage, simpler docs layout that no longer collapses sections of the sidebar, and more prominent examples of [Bootstrap Icons](https://icons.getbootstrap.com).
-
-### More CSS variables
-
-**We’ve updated all our components to use CSS variables.** While Sass still underpins everything, each component has been updated to include CSS variables on the component base classes (e.g., `.btn`), allowing for more real-time customization of Bootstrap. In subsequent releases, we'll continue to expand our use of CSS variables into our layout, forms, helpers, and utilities. Read more about CSS variables in each component on their respective documentation pages.
-
-Our CSS variable usage will be somewhat incomplete until Bootstrap 6. While we’d love to fully implement these across the board, they do run the risk of causing breaking changes. For example, setting `$alert-border-width: var(--bs-border-width)` in our source code breaks potential Sass in your own code if you were doing `$alert-border-width * 2` for some reason.
-
-As such, wherever possible, we will continue to push towards more CSS variables, but please recognize our implementation may be slightly limited in v5.
-
-### New `_maps.scss`
-
-**Bootstrap v5.2.0 introduced a new Sass file with `_maps.scss`.** It pulls out several Sass maps from `_variables.scss` to fix an issue where updates to an original map were not applied to secondary maps that extend them. For example, updates to `$theme-colors` were not being applied to other theme maps that relied on `$theme-colors`, breaking key customization workflows. In short, Sass has a limitation where once a default variable or map has been _used_, it cannot be updated. _There’s a similar shortcoming with CSS variables when they’re used to compose other CSS variables._
-
-This is why variable customizations in Bootstrap have to come after `@import "functions"`, but before `@import "variables"` and the rest of our import stack. The same applies to Sass maps—you must override the defaults before they get used. The following maps have been moved to the new `_maps.scss`:
-
-- `$theme-colors-rgb`
-- `$utilities-colors`
-- `$utilities-text`
-- `$utilities-text-colors`
-- `$utilities-bg`
-- `$utilities-bg-colors`
-- `$negative-spacers`
-- `$gutters`
-
-Your custom Bootstrap CSS builds should now look something like this with a separate maps import.
-
-```diff
-  // Functions come first
-  @import "functions";
-
-  // Optional variable overrides here
-+ $custom-color: #df711b;
-+ $custom-theme-colors: (
-+   "custom": $custom-color
-+ );
-
-  // Variables come next
-  @import "variables";
-
-+ // Optional Sass map overrides here
-+ $theme-colors: map-merge($theme-colors, $custom-theme-colors);
-+
-+ // Followed by our default maps
-+ @import "maps";
-+
-  // Rest of our imports
-  @import "mixins";
-  @import "utilities";
-  @import "root";
-  @import "reboot";
-  // etc
-```
-
-### New utilities
-
-- Expanded [`font-weight` utilities]([[docsref:/utilities/text#font-weight-and-italics]]) to include `.fw-semibold` for semibold fonts.
-- Expanded [`border-radius` utilities]([[docsref:/utilities/border-radius#sizes]]) to include two new sizes, `.rounded-4` and `.rounded-5`, for more options.
-
-### Additional changes
-
-- **Introduced new `$enable-container-classes` option. —** Now when opting into the experimental CSS Grid layout, `.container-*` classes will still be compiled, unless this option is set to `false`. Containers also now keep their gutter values.
-
-- **Offcanvas component now has [responsive variations]([[docsref:/components/offcanvas#responsive]]).** The original `.offcanvas` class remains unchanged—it hides content across all viewports. To make it responsive, change that `.offcanvas` class to any `.offcanvas-{sm|md|lg|xl|xxl}` class.
-
-- **Thicker table dividers are now opt-in. —** We’ve removed the thicker and more difficult to override border between table groups and moved it to an optional class you can apply, `.table-group-divider`. [See the table docs for an example.]([[docsref:/content/tables#table-group-dividers]])
-
-- **[Scrollspy has been rewritten](https://github.com/twbs/bootstrap/pull/33421) to use the Intersection Observer API**, which means you no longer need relative parent wrappers, deprecates `offset` config, and more. Look for your Scrollspy implementations to be more accurate and consistent in their nav highlighting.
-
-- **Popovers and tooltips now use CSS variables.** Some CSS variables have been updated from their Sass counterparts to reduce the number of variables. As a result, three variables have been deprecated in this release: `$popover-arrow-color`, `$popover-arrow-outer-color`, and `$tooltip-arrow-color`.
-
-- **Added new `.text-bg-{color}` helpers.** Instead of setting individual `.text-*` and `.bg-*` utilities, you can now use [the `.text-bg-*` helpers]([[docsref:helpers/color-background]]) to set a `background-color` with contrasting foreground `color`.
-
-- Added `.form-check-reverse` modifier to flip the order of labels and associated checkboxes/radios.
-
-- Added [striped columns]([[docsref:/content/tables#striped-columns]]) support to tables via the new `.table-striped-columns` class.
-
-For a complete list of changes, [see the v5.2.0 project on GitHub](https://github.com/twbs/bootstrap/projects/32).
-
-## v5.1.0
-
-<hr class="mb-4"/>
-
-- **Added experimental support for [CSS Grid layout]([[docsref:/layout/css-grid]]). —** This is a work in progress, and is not yet ready for production use, but you can opt into the new feature via Sass. To enable it, disable the default grid, by setting `$enable-grid-classes: false` and enable the CSS Grid by setting `$enable-cssgrid: true`.
-
-- **Updated navbars to support offcanvas. —** Add [offcanvas drawers in any navbar]([[docsref:/components/navbar#offcanvas]]) with the responsive `.navbar-expand-*` classes and some offcanvas markup.
-
-- **Added new [placeholder component]([[docsref:/components/placeholders/]]). —** Our newest component, a way to provide temporary blocks in lieu of real content to help indicate that something is still loading in your site or app.
-
-- **Collapse plugin now supports [horizontal collapsing]([[docsref:/components/collapse#horizontal]]). —** Add `.collapse-horizontal` to your `.collapse` to collapse the `width` instead of the `height`. Avoid browser repainting by setting a `min-height` or `height`.
-
-- **Added new stack and vertical rule helpers. —** Quickly apply multiple flexbox properties to quickly create custom layouts with [stacks]([[docsref:/helpers/stacks/]]). Choose from horizontal (`.hstack`) and vertical (`.vstack`) stacks. Add vertical dividers similar to `<hr>` elements with the [new `.vr` helpers]([[docsref:/helpers/vertical-rule/]]).
-
-- **Added new global `:root` CSS variables. —** Added several new CSS variables to the `:root` level for controlling `<body>` styles. More are in the works, including across our utilities and components, but for now read up [CSS variables in the Customize section]([[docsref:/customize/css-variables/]]).
-
-- **Overhauled color and background utilities to use CSS variables, and added new [text opacity]([[docsref:/utilities/text#opacity]]) and [background opacity]([[docsref:/utilities/background#opacity]]) utilities. —** `.text-*` and `.bg-*` utilities are now built with CSS variables and `rgba()` color values, allowing you to easily customize any utility with new opacity utilities.
-
-- **Added new snippet examples based to show how to customize our components. —** Pull ready to use customized components and other common design patterns with our new [Snippets examples]([[docsref:/examples/#snippets]]). Includes [footers]([[docsref:/examples/footers/]]), [dropdowns]([[docsref:/examples/dropdowns/]]), [list groups]([[docsref:/examples/list-groups/]]), and [modals]([[docsref:/examples/modals/]]).
-
-- **Removed unused positioning styles from popovers and tooltips** as these are handled solely by Popper. `$tooltip-margin` has been deprecated and set to `null` in the process.

-
-### Documentation changes
-
-- Redesigned homepage, docs layout, and footer.
-- Added [new Parcel guide]([[docsref:/getting-started/parcel]]).
-- Added [new Customize section]([[docsref:/customize/overview/]]), replacing [v4’s Theming page](https://getbootstrap.com/docs/4.6/getting-started/theming/), with new details on Sass, global configuration options, color schemes, CSS variables, and more.
-- Reorganized all form documentation into [new Forms section]([[docsref:/forms/overview/]]), breaking apart the content into more focused pages.
-- Similarly, updated [the Layout section]([[docsref:/layout/breakpoints]]), to flesh out grid content more clearly.
-- Renamed “Navs” component page to "Navs & Tabs".
-- Renamed “Checks” page to "Checks & radios".
-- Redesigned the navbar and added a new subnav to make it easier to get around our sites and docs versions.
-- Added new keyboard shortcut for the search field: <kbd><kbd>Ctrl</kbd> + <kbd>/</kbd></kbd>.
+- **Implemented CSS layers** in `_root.scss` and applied them to all our Sass files.
+  - Layers are set in `_root.scss` and then utilized across separate Sass partials.
+  - We cannot, unfortunately, wrap `@use` or `@forward` statements in `@layer`—Sass expects those to be top level at all times. Also, while CSS allows `@import "file.css" layer(name)`, Sass also does not support that.
+- Clarified and simplified CSS-Sass setup.
+- New, streamlined color modes and theming.
+  - Removed `_maps.scss`
+  - Removed `_variables-dark.scss`
+  - Added `_colors.scss`, splitting them out from `_variables.scss`,
+  - Added `_theme.scss` where we setup all our global theming for how colors are applied
+- **Updated lg, xl, and 2xl breakpoints and containers.**
+  - Increased the `lg` breakpoint from 992px to 1024px; it's container remains the same at 960px.
+  - Increased the `xl` breakpoint from 1200px to 1280px, and it's container from 1140px to 1200px.
+  - Renamed `xxl` to `2xl` for better scaling with additional custom breakpoints
+  - Increased the `2xl` breakpoint from 1400px to 1536px, and it's container from 1320px to 1440px.
 
 ### Sass
 
-- We’ve ditched the default Sass map merges to make it easier to remove redundant values. Keep in mind you now have to define all values in the Sass maps like `$theme-colors`. Check out how to deal with [Sass maps]([[docsref:/customize/sass#maps-and-loops]]).
+- Dropped support for Node Sass, including no longer testing any of our source CSS against it.
+  - Rearranged several Sass files in the process.
+- Removed `add()` and `subtract()` functions. Use `calc()` instead.
+- **Removes all deprecated Sass variables and values:**
+  - Removed `$variable-prefix`, use `$prefix` instead.
+  - Removed `$nested-kbd-font-weight`, no replacement.
+  - Removed `muted`, `black-50`, and `white-50` from text colors utilities map
+  - Consolidated carousel dark variables, removing `$carousel-dark-indicator-active-bg`, `$carousel-dark-caption-color`, and `$carousel-dark-control-icon-filter` for their reassigned counterparts.
+  - Removed `$btn-close-white-filter` for `$btn-close-filter-dark`.
+  - Removed `$border-radius-2xl`, use `$border-radius-xxl`.
+  - Removed `$text-muted` for secondary color.
+  - Removed `$hr-bg-color` for `$hr-border-color` and `$hr-height` for `$hr-border-width`.
+  - Removed unused `$dropdown-header-padding` for the `-x`/`-y` split variables.
+  - Removed unused `$accordion-button-focus-border-color`.
+  - Removed unused `$tooltip-arrow-color`.
+  - Removed unused `$popover-arrow-color` and `$popover-arrow-outer-color`
+  - Removed unused `$alert-bg-scale`, `$alert-border-scale`, and `$alert-color-scale` (replaced by theme tokens)
+  - Removed unused `$list-group-item-bg-scale` and `$list-group-item-color-scale` (replaced by theme tokens)
 
-- <span class="badge text-bg-danger">Breaking</span> Renamed `color-yiq()` function and related variables to `color-contrast()` as it’s no longer related to YIQ color space. [See #30168.](https://github.com/twbs/bootstrap/pull/30168/)
-  - `$yiq-contrasted-threshold` is renamed to `$min-contrast-ratio`.
-  - `$yiq-text-dark` and `$yiq-text-light` are respectively renamed to `$color-contrast-dark` and `$color-contrast-light`.
+### Reboot
 
-- <span class="badge text-bg-danger">Breaking</span> Media query mixins parameters have changed for a more logical approach.
-  - `media-breakpoint-down()` uses the breakpoint itself instead of the next breakpoint (e.g., `media-breakpoint-down(lg)` instead of `media-breakpoint-down(md)` targets viewports smaller than `lg`).
-  - Similarly, the second parameter in `media-breakpoint-between()` also uses the breakpoint itself instead of the next breakpoint (e.g., `media-breakpoint-between(sm, lg)` instead of `media-breakpoint-between(sm, md)` targets viewports between `sm` and `lg`).
-
-- <span class="badge text-bg-danger">Breaking</span> Removed print styles and `$enable-print-styles` variable. Print display classes are still around. [See #28339](https://github.com/twbs/bootstrap/pull/28339).
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `color()`, `theme-color()`, and `gray()` functions in favor of variables. [See #29083](https://github.com/twbs/bootstrap/pull/29083).
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `theme-color-level()` function to `color-level()` and now accepts any color you want instead of only `$theme-color` colors. [See #29083](https://github.com/twbs/bootstrap/pull/29083) **Watch out:** `color-level()` was later on dropped in `v5.0.0-alpha3`.
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `$enable-prefers-reduced-motion-media-query` and `$enable-pointer-cursor-for-buttons` to `$enable-reduced-motion` and `$enable-button-pointers` for brevity.
-
-- <span class="badge text-bg-danger">Breaking</span> Removed the `bg-gradient-variant()` mixin. Use the `.bg-gradient` class to add gradients to elements instead of the generated `.bg-gradient-*` classes.
-
-- <span class="badge text-bg-danger">Breaking</span> **Removed previously deprecated mixins:**
-  - `hover`, `hover-focus`, `plain-hover-focus`, and `hover-focus-active`
-  - `float()`
-  - `form-control-mixin()`
-  - `nav-divider()`
-  - `retina-img()`
-  - `text-hide()` (also dropped the associated utility class, `.text-hide`)
-  - `visibility()`
-  - `form-control-focus()`
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `scale-color()` function to `shift-color()` to avoid collision with Sass’s own color scaling function.
-
-- `box-shadow` mixins now allow `null` values and drop `none` from multiple arguments. [See #30394](https://github.com/twbs/bootstrap/pull/30394).
-
-- The `border-radius()` mixin now has a default value.
-
-### Color system
-
-- The color system which worked with `color-level()` and `$theme-color-interval` was removed in favor of a new color system. All `lighten()` and `darken()` functions in our codebase are replaced by `tint-color()` and `shade-color()`. These functions will mix the color with either white or black instead of changing its lightness by a fixed amount. The `shift-color()` will either tint or shade a color depending on whether its weight parameter is positive or negative. [See #30622](https://github.com/twbs/bootstrap/pull/30622) for more details.
-
-- Added new tints and shades for every color, providing nine separate colors for each base color, as new Sass variables.
-
-- Improved color contrast. Bumped color contrast ratio from 3:1 to 4.5:1 and updated blue, green, cyan, and pink colors to ensure WCAG 2.2 AA contrast. Also changed our color contrast color from `$gray-900` to `$black`.
-
-- To support our color system, we’ve added new custom `tint-color()` and `shade-color()` functions to mix our colors appropriately.
-
-### Grid updates
-
-- **New breakpoint!** Added new `xxl` breakpoint for `1400px` and up. No changes to all other breakpoints.
-
-- **Improved gutters.** Gutters are now set in rems, and are narrower than v4 (`1.5rem`, or about `24px`, down from `30px`). This aligns our grid system’s gutters with our spacing utilities.
-  - Added new [gutter class]([[docsref:/layout/gutters]]) (`.g-*`, `.gx-*`, and `.gy-*`) to control horizontal/vertical gutters, horizontal gutters, and vertical gutters.
-  - <span class="badge text-bg-danger">Breaking</span> Renamed `.no-gutters` to `.g-0` to match new gutter utilities.
-
-- Columns no longer have `position: relative` applied, so you may have to add `.position-relative` to some elements to restore that behavior.
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped several `.order-*` classes that often went unused. We now only provide `.order-0` to `.order-5` out of the box.
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped the `.media` component as it can be easily replicated with utilities. [See #28265](https://github.com/twbs/bootstrap/pull/28265) and the [flex utilities page for an example]([[docsref:/utilities/flex#media-object]]).
-
-- <span class="badge text-bg-danger">Breaking</span> `bootstrap-grid.css` now only applies `box-sizing: border-box` to the column instead of resetting the global box-sizing. This way, our grid styles can be used in more places without interference.
-
-- `$enable-grid-classes` no longer disables the generation of container classes anymore. [See #29146.](https://github.com/twbs/bootstrap/pull/29146)
-
-- Updated the `make-col` mixin to default to equal columns without a specified size.
-
-### Content, Reboot, etc
-
-- **[RFS]([[docsref:/getting-started/rfs]]) is now enabled by default.** Headings using the `font-size()` mixin will automatically adjust their `font-size` to scale with the viewport. _This feature was previously opt-in with v4._
-
-- <span class="badge text-bg-danger">Breaking</span> Overhauled our display typography to replace our `$display-*` variables and with a `$display-font-sizes` Sass map. Also removed the individual `$display-*-weight` variables for a single `$display-font-weight` and adjusted `font-size`s.
-
-- Added two new `.display-*` heading sizes, `.display-5` and `.display-6`.
-
-- **Links are underlined by default** (not just on hover), unless they’re part of specific components.
-
-- **Redesigned tables** to refresh their styles and rebuild them with CSS variables for more control over styling.
-
-- <span class="badge text-bg-danger">Breaking</span> Nested tables do not inherit styles anymore.
-
-- <span class="badge text-bg-danger">Breaking</span> `.thead-light` and `.thead-dark` are dropped in favor of the `.table-*` variant classes which can be used for all table elements (`thead`, `tbody`, `tfoot`, `tr`, `th` and `td`).
-
-- <span class="badge text-bg-danger">Breaking</span> The `table-row-variant()` mixin is renamed to `table-variant()` and accepts only 2 parameters: `$color` (color name) and `$value` (color code). The border color and accent colors are automatically calculated based on the table factor variables.
-
-- Split table cell padding variables into `-y` and `-x`.
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `.pre-scrollable` class. [See #29135](https://github.com/twbs/bootstrap/pull/29135)
-
-- <span class="badge text-bg-danger">Breaking</span> `.text-*` utilities do not add hover and focus states to links anymore. `.link-*` helper classes can be used instead. [See #29267](https://github.com/twbs/bootstrap/pull/29267)
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `.text-justify` class. [See #29793](https://github.com/twbs/bootstrap/pull/29793)
-
-- <span class="badge text-bg-danger">Breaking</span> ~~`<hr>` elements now use `height` instead of `border` to better support the `size` attribute. This also enables use of padding utilities to create thicker dividers (e.g., `<hr class="py-1">`).~~
-
-- Reset default horizontal `padding-left` on `<ul>` and `<ol>` elements from browser default `40px` to `2rem`.
-
-- Added `$enable-smooth-scroll`, which applies `scroll-behavior: smooth` globally—except for users asking for reduced motion through `prefers-reduced-motion` media query. [See #31877](https://github.com/twbs/bootstrap/pull/31877)
-
-### RTL
-
-- Horizontal direction specific variables, utilities, and mixins have all been renamed to use logical properties like those found in flexbox layouts—e.g., `start` and `end` in lieu of `left` and `right`.
+- Relocated heading classes (like `.h1`) and some type classes (`.mark` and `.small`) to Reboot from `_type.scss`. This avoids a dependency in Sass modules and we like to avoid extending selectors in general.
 
 ### Forms
 
-- **Added new floating forms!** We’ve promoted the Floating labels example to fully supported form components. [See the new Floating labels page.]([[docsref:/forms/floating-labels]])
-
-- <span class="badge text-bg-danger">Breaking</span> **Consolidated native and custom form elements.** Checkboxes, radios, selects, and other inputs that had native and custom classes in v4 have been consolidated. Now nearly all our form elements are entirely custom, most without the need for custom HTML.
-  - `.custom-control.custom-checkbox` is now `.form-check`.
-  - `.custom-control.custom-radio` is now `.form-check`.
-  - `.custom-control.custom-switch` is now `.form-check.form-switch`.
-  - `.custom-select` is now `.form-select`.
-  - `.custom-file` and `.form-control-file` have been replaced by custom styles on top of `.form-control`.
-  - `.custom-range` is now `.form-range`.
-  - Dropped native `.form-control-file` and `.form-control-range`.
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `.input-group-append` and `.input-group-prepend`. You can now just add buttons and `.input-group-text` as direct children of the input groups.
-
-- The longstanding [Missing border radius on input group with validation feedback bug](https://github.com/twbs/bootstrap/issues/25110) is finally fixed by adding an additional `.has-validation` class to input groups with validation.
-
-- <span class="badge text-bg-danger">Breaking</span> **Dropped form-specific layout classes for our grid system.** Use our grid and utilities instead of `.form-group`, `.form-row`, or `.form-inline`.
-
-- <span class="badge text-bg-danger">Breaking</span> Form labels now require `.form-label`.
-
-- <span class="badge text-bg-danger">Breaking</span> `.form-text` no longer sets `display`, allowing you to create inline or block help text as you wish just by changing the HTML element.
-
-- Form controls no longer used fixed `height` when possible, instead deferring to `min-height` to improve customization and compatibility with other components.
-
-- Validation icons are no longer applied to `<select>`s with `multiple`.
-
-- Rearranged source Sass files under `scss/forms/`, including input group styles.
-
-<hr class="my-5"/>
-
-### Components
-
-- Unified `padding` values for alerts, breadcrumbs, cards, dropdowns, list groups, modals, popovers, and tooltips to be based on our `$spacer` variable. [See #30564](https://github.com/twbs/bootstrap/pull/30564).
-
-#### Accordion
-
-- Added [new accordion component]([[docsref:/components/accordion]]).
-
-#### Alerts
-
-- Alerts now have [examples with icons]([[docsref:/components/alerts#icons]]).
-
-- Removed custom styles for `<hr>`s in each alert since they already use `currentColor`.
-
-#### Badges
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped all `.badge-*` color classes for background utilities (e.g., use `.bg-primary` instead of `.badge-primary`).
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `.badge-pill`—use the `.rounded-pill` utility instead.
-
-- <span class="badge text-bg-danger">Breaking</span> Removed hover and focus styles for `<a>` and `<button>` elements.
-
-- Increased default padding for badges from `.25em`/`.5em` to `.35em`/`.65em`.
-
-#### Breadcrumbs
-
-- Simplified the default appearance of breadcrumbs by removing `padding`, `background-color`, and `border-radius`.
-
-- Added new CSS custom property `--bs-breadcrumb-divider` for easy customization without needing to recompile CSS.
-
-#### Buttons
-
-- <span class="badge text-bg-danger">Breaking</span> **[Toggle buttons]([[docsref:/forms/checks-radios#toggle-buttons]]), with checkboxes or radios, no longer require JavaScript and have new markup.** We no longer require a wrapping element, add `.btn-check` to the `<input>`, and pair it with any `.btn` classes on the `<label>`. [See #30650](https://github.com/twbs/bootstrap/pull/30650). _The docs for this has moved from our Buttons page to the new Forms section._
-
-- <span class="badge text-bg-danger">Breaking</span> **Dropped `.btn-block` for utilities.** Instead of using `.btn-block` on the `.btn`, wrap your buttons with `.d-grid` and a `.gap-*` utility to space them as needed. Switch to responsive classes for even more control over them. [Read the docs for some examples.]([[docsref:/components/buttons#block-buttons]])
-
-- Updated our `button-variant()` and `button-outline-variant()` mixins to support additional parameters.
-
-- Updated buttons to ensure increased contrast on hover and active states.
-
-- Disabled buttons now have `pointer-events: none;`.
-
-#### Card
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `.card-deck` in favor of our grid. Wrap your cards in column classes and add a parent `.row-cols-*` container to recreate card decks (but with more control over responsive alignment).
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `.card-columns` in favor of Masonry. [See #28922](https://github.com/twbs/bootstrap/pull/28922).
-
-- <span class="badge text-bg-danger">Breaking</span> Replaced the `.card` based accordion with a [new Accordion component]([[docsref:/components/accordion]]).
-
-#### Carousel
-
-- Added new [`.carousel-dark` variant]([[docsref:/components/carousel#dark-variant]]) for dark text, controls, and indicators (great for lighter backgrounds).
-
-- Replaced chevron icons for carousel controls with new SVGs from [Bootstrap Icons]([[config:icons]]).
-
-#### Close button
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `.close` to `.btn-close` for a less generic name.
-
-- Close buttons now use a `background-image` (embedded SVG) instead of a `&times;` in the HTML, allowing for easier customization without the need to touch your markup.
-
-- Added new `.btn-close-white` variant that uses `filter: invert(1)` to enable higher contrast dismiss icons against darker backgrounds.
-
-#### Collapse
-
-- Removed scroll anchoring for accordions.
-
-#### Dropdowns
-
-- Added new `.dropdown-menu-dark` variant and associated variables for on-demand dark dropdowns.
-
-- Added new variable for `$dropdown-padding-x`.
-
-- Darkened the dropdown divider for improved contrast.
-
-- <span class="badge text-bg-danger">Breaking</span> All the events for the dropdown are now triggered on the dropdown toggle button and then bubbled up to the parent element.
-
-- Dropdown menus now have a `data-bs-popper="static"` attribute set when the positioning of the dropdown is static, or dropdown is in the navbar. This is added by our JavaScript and helps us use custom position styles without interfering with Popper’s positioning.
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped `flip` option for dropdown plugin in favor of native Popper configuration. You can now disable the flipping behavior by passing an empty array for [`fallbackPlacements`](https://popper.js.org/docs/v2/modifiers/flip/#fallbackplacements) option in [flip](https://popper.js.org/docs/v2/modifiers/flip/) modifier.
-
-- Dropdown menus can now be clickable with a new `autoClose` option to handle the [auto close behavior]([[docsref:/components/dropdowns#auto-close-behavior]]). You can use this option to accept the click inside or outside the dropdown menu to make it interactive.
-
-- Dropdowns now support `.dropdown-item`s wrapped in `<li>`s.
-
-#### Jumbotron
-
-- <span class="badge text-bg-danger">Breaking</span> Dropped the jumbotron component as it can be replicated with utilities. [See our new Jumbotron example for a demo.]([[docsref:/examples/jumbotron]])
-
-#### List group
-
-- Added new [`.list-group-numbered` modifier]([[docsref:/components/list-group#numbered]]) to list groups.
-
-#### Navs and tabs
-
-- Added new `null` variables for `font-size`, `font-weight`, `color`, and `:hover` `color` to the `.nav-link` class.
-
-#### Navbars
-
-- <span class="badge text-bg-danger">Breaking</span> Navbars now require a container within (to drastically simplify spacing requirements and CSS required).
-- <span class="badge text-bg-danger">Breaking</span> The `.active` class can no longer be applied to `.nav-item`s, it must be applied directly on `.nav-link`s.
-
-#### Offcanvas
-
-- Added the new [offcanvas component]([[docsref:/components/offcanvas]]).
-
-#### Pagination
-
-- Pagination links now have customizable `margin-left` that are dynamically rounded on all corners when separated from one another.
-
-- Added `transition`s to pagination links.
-
-#### Popovers
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `.arrow` to `.popover-arrow` in our default popover template.
-
-- Renamed `whiteList` option to `allowList`.
-
-#### Spinners
-
-- Spinners now honor `prefers-reduced-motion: reduce` by slowing down animations. [See #31882](https://github.com/twbs/bootstrap/pull/31882).
-
-- Improved spinner vertical alignment.
-
-#### Toasts
-
-- Toasts can now be [positioned]([[docsref:/components/toasts#placement]]) in a `.toast-container` with the help of [positioning utilities]([[docsref:/utilities/position]]).
-
-- Changed default toast duration to 5 seconds.
-
-- Removed `overflow: hidden` from toasts and replaced with proper `border-radius`s with `calc()` functions.
-
-#### Tooltips
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `.arrow` to `.tooltip-arrow` in our default tooltip template.
-
-- <span class="badge text-bg-danger">Breaking</span> The default value for the `fallbackPlacements` is changed to `['top', 'right', 'bottom', 'left']` for better placement of popper elements.
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `whiteList` option to `allowList`.
-
-### Utilities
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed several utilities to use logical property names instead of directional names with the addition of RTL support:
-  - Renamed `.float-left` and `.float-right` to `.float-start` and `.float-end`.
-  - Renamed `.border-left` and `.border-right` to `.border-start` and `.border-end`.
-  - Renamed `.rounded-left` and `.rounded-right` to `.rounded-start` and `.rounded-end`.
-  - Renamed `.ml-*` and `.mr-*` to `.ms-*` and `.me-*`.
-  - Renamed `.pl-*` and `.pr-*` to `.ps-*` and `.pe-*`.
-  - Renamed `.text-*-left` and `.text-*-right` to `.text-*-start` and `.text-*-end`.
-
-- <span class="badge text-bg-danger">Breaking</span> Disabled negative margins by default.
-
-- Added new `.bg-body` class for quickly setting the `<body>`’s background to additional elements.
-
-- Added new [position utilities]([[docsref:/utilities/position#arrange-elements]]) for `top`, `right`, `bottom`, and `left`. Values include `0`, `50%`, and `100%` for each property.
-
-- Added new `.translate-middle-x` & `.translate-middle-y` utilities to horizontally or vertically center absolute/fixed positioned elements.
-
-- Added new [`border-width` utilities]([[docsref:/utilities/border#border-width]]).
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `.text-monospace` to `.font-monospace`.
-
-- <span class="badge text-bg-danger">Breaking</span> Removed `.text-hide` as it’s an antiquated method for hiding text that shouldn’t be used anymore.
-
-- Added `.fs-*` utilities for `font-size` utilities (with RFS enabled). These use the same scale as HTML’s default headings (1-6, large to small), and can be modified via Sass map.
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `.font-weight-*` utilities as `.fw-*` for brevity and consistency.
-
-- <span class="badge text-bg-danger">Breaking</span> Renamed `.font-italic` utility to `.fst-italic` for brevity and consistency with new `.fst-normal` utility.
-
-- Added `.d-grid` to display utilities and new `gap` utilities (`.gap`) for CSS Grid and flexbox layouts.
-
-- <span class="badge text-bg-danger">Breaking</span> Removed `.rounded-sm` and `rounded-lg`, and introduced a new scale of classes, `.rounded-0` to `.rounded-3`. [See #31687](https://github.com/twbs/bootstrap/pull/31687).
-
-- Added new `line-height` utilities: `.lh-1`, `.lh-sm`, `.lh-base` and `.lh-lg`. See [text utilities]([[docsref:/utilities/text#line-height]]).
-
-- Moved the `.d-none` utility in our CSS to give it more weight over other display utilities.
-
-- Extended the `.visually-hidden-focusable` helper to also work on containers, using `:focus-within`.
+- **Refactor checks, radios, and switches.**
+  - Split apart `_form-check.scss` into separate stylesheets: `_checkbox.scss`, `_radio.scss`, and `_switch.scss`.
+  - Also split apart the documentation pages for checks, radios, and switches.
+  - Added new CSS variables on each of these components. _Side note: we could've shared variables here, but chose not to for simplicity's sake._
+  - Removed several now unused Sass variables.
+  - Checkboxes now have a wrapping element and an SVG in the DOM for checked and indeterminate states. Radios and switches do not.
+  - Revamped layout for checks, radios, and switches with labels (and descriptions). We now have custom elements for layout that include basic flexbox styling.
+  - @mdo-do: Decide on fate of `.form-check-reverse` and `.btn-check`
+- **Consolidate `.form-select` into `.form-control`.**
+  - Removed `.form-select`—use `.form-control` on `<select>` elements now. Too much abstraction and duplication at the same time.
+  - Adds new CSS variables on `.form-control` for easier customization without Sass compilation.
+  - `.form-control` now has a `min-height` at all times as opposed to just on `<textarea>` elements. This reduces some CSS for us.
 
 ### Helpers
 
-- <span class="badge text-bg-danger">Breaking</span> **Responsive embed helpers have been renamed to [ratio helpers]([[docsref:/utilities/aspect-ratio]])** with new class names and improved behaviors, as well as a helpful CSS variable.
-  - Classes have been renamed to change `by` to `x` in the aspect ratio. For example, `.ratio-16by9` is now `.ratio-16x9`.
-  - We’ve dropped the `.embed-responsive-item` and element group selector in favor of a simpler `.ratio > *` selector. No more class is needed, and the ratio helper now works with any HTML element.
-  - The `$embed-responsive-aspect-ratios` Sass map has been renamed to `$aspect-ratios` and its values have been simplified to include the class name and the percentage as the `key: value` pair.
-  - CSS variables are now generated and included for each value in the Sass map. Modify the `--bs-aspect-ratio` variable on the `.ratio` to create any [custom aspect ratio]([[docsref:/utilities/aspect-ratio#custom-ratios]]).
+- Ratio helpers have been moved to utilities.
+- Dropped clearfix helper for `.d-flow-root` utility.
 
-- <span class="badge text-bg-danger">Breaking</span> **"Screen reader" classes are now ["visually hidden" classes]([[docsref:/helpers/visually-hidden]]).**
-  - Changed the Sass file from `scss/helpers/_screenreaders.scss` to `scss/helpers/_visually-hidden.scss`
-  - Renamed `.sr-only` and `.sr-only-focusable` to `.visually-hidden` and `.visually-hidden-focusable`
-  - Renamed `sr-only()` and `sr-only-focusable()` mixins to `visually-hidden()` and `visually-hidden-focusable()`.
+### Utilities
 
-- `bootstrap-utilities.css` now also includes our helpers. Helpers don’t need to be imported in custom builds anymore.
+- Ratio helpers are now powered by the utility API and use simplified values without `calc()`.
+- mdo-do: Need to refactor utilities API if we want to restore the commented out custom ratios.
+- **Display utilities:** added `flow-root` option for a modern clearfix.
+- **Sizing utilities:**
+  - Renamed `.mh-*`/`.mw-*` to `.max-h-*`/`.max-w-*`
+  - Added `.min-h-*` and `.min-w-*` utilities with two default values, `0` and `100%`
+  - Added `auto`, `min-content`, `max-content`, and `fit-content` to `width` and `height` utilities.
+- **Flex & Grid utilities:**
+  - Added `.place-items` and `.justify-items` utilities.
 
-### JavaScript
+### Docs
 
-- **Dropped jQuery dependency** and rewrote plugins to be in regular JavaScript.
-
-- <span class="badge text-bg-danger">Breaking</span> Data attributes for all JavaScript plugins are now namespaced to help distinguish Bootstrap functionality from third parties and your own code. For example, we use `data-bs-toggle` instead of `data-toggle`.
-
-- **All plugins can now accept a CSS selector as the first argument.** You can either pass a DOM element or any valid CSS selector to create a new instance of the plugin:
-
-  ```js
-  const modal = new bootstrap.Modal('#myModal')
-  const dropdown = new bootstrap.Dropdown('[data-bs-toggle="dropdown"]')
-  ```
-
-- `popperConfig` can be passed as a function that accepts the Bootstrap’s default Popper config as an argument, so that you can merge this default configuration in your way. **Applies to dropdowns, popovers, and tooltips.**
-
-- The default value for the `fallbackPlacements` is changed to `['top', 'right', 'bottom', 'left']` for better placement of Popper elements. **Applies to dropdowns, popovers, and tooltips.**
-
-- Removed underscore from public static methods like `_getInstance()` → `getInstance()`.
-
-- Removed `util.js`, with its functionality now integrated into individual plugins. If you previously included `util.js` manually, you can safely remove it, as it is no longer needed. Each plugin now contains only the utilities it requires, enhancing modularity and reducing dependencies.
+- Removed all `AddedIn` badges.
+- Rearranged utilities documentation to break apart larger pages that included groups of utilities. Sizing, spacing, flex, type, and more have been broken out into smaller pages with new sub-group headings in the sidebar.

+## Overview
+
+Use `align-content` utilities on flexbox containers to align flex items _together_ on the cross axis. Choose from `start` (browser default), `end`, `center`, `between`, `around`, or `stretch`. To demonstrate these utilities, we've enforced `flex-wrap: wrap` and increased the number of flex items.
+
+**Heads up!** This property has no effect on single rows of flex items.
+

+Use `align-self` utilities on flexbox items to individually change their alignment on the cross axis (the y-axis to start, x-axis if `flex-direction: column`). Choose from the same options as `align-items`: `start`, `end`, `center`, `baseline`, or `stretch` (browser default).

-
-<ul>
-{getData('breakpoints').map((breakpoint) => ['first', 'last'].map((value) => {
-  return (
-    <li><code>.order{breakpoint.abbr}-{value}</code></li>
-  )
-}))}
-</ul>
-
-## Align content
-
-Use `align-content` utilities on flexbox containers to align flex items _together_ on the cross axis. Choose from `start` (browser default), `end`, `center`, `between`, `around`, or `stretch`. To demonstrate these utilities, we’ve enforced `flex-wrap: wrap` and increased the number of flex items.
-
-**Heads up!** This property has no effect on single rows of flex items.

-## Media object
-
-Looking to replicate the [media object component](https://getbootstrap.com/docs/4.6/components/media-object/) from Bootstrap 4? Recreate it in no time with a few flex utilities that allow even more flexibility and customization than before.
-
-<Example code={`<div class="d-flex">
-    <div class="flex-shrink-0">
-      <Placeholder width="100" height="100" color="#999" background="#e5e5e5" text="Image" />
-    </div>
-    <div class="flex-grow-1 ms-3">
-      This is some content from a media component. You can replace this with any content and adjust it as needed.
-    </div>
-  </div>`} />
-
-And say you want to vertically center the content next to the image:
-
-<Example code={`<div class="d-flex align-items-center">
-    <div class="flex-shrink-0">
-      <Placeholder width="100" height="100" color="#999" background="#e5e5e5" text="Image" />

+
+## Font size
+
+Quickly change the `font-size` of text. While our heading classes (e.g., `.h1`–`.h6`) apply `font-size`, `font-weight`, and `line-height`, these utilities _only_ apply `font-size`. Sizing for these utilities matches HTML's heading elements, so as the number increases, their size decreases.
+
+<Example code={`<p class="fs-1">.fs-1 text</p>
+<p class="fs-2">.fs-2 text</p>
+<p class="fs-3">.fs-3 text</p>
+<p class="fs-4">.fs-4 text</p>
+<p class="fs-5">.fs-5 text</p>
+<p class="fs-6">.fs-6 text</p>`} />
+
+Customize your available `font-size`s by modifying the `$font-sizes` Sass map.
+
+## Font weight and italics
+
+Quickly change the `font-weight` or `font-style` of text with these utilities. `font-style` utilities are abbreviated as `.fst-*` and `font-weight` utilities are abbreviated as `.fw-*`.
+
+<Example code={`<p class="fw-bold">Bold text.</p>
+<p class="fw-bolder">Bolder weight text (relative to the parent element).</p>
+<p class="fw-semibold">Semibold weight text.</p>
+<p class="fw-medium">Medium weight text.</p>
+<p class="fw-normal">Normal weight text.</p>
+<p class="fw-light">Light weight text.</p>
+<p class="fw-lighter">Lighter weight text (relative to the parent element).</p>
+<p class="fst-italic">Italic text.</p>
+<p class="fst-normal">Text with normal font style</p>`} />
+
+## Line height
+
+Change the line height with `.lh-*` utilities.
+
+<Example code={`<p class="lh-1">This is a long paragraph written to show how the line-height of an element is affected by our utilities. Classes are applied to the element itself or sometimes the parent element. These classes can be customized as needed with our utility API.</p>
+<p class="lh-sm">This is a long paragraph written to show how the line-height of an element is affected by our utilities. Classes are applied to the element itself or sometimes the parent element. These classes can be customized as needed with our utility API.</p>

+<p class="lh-lg">This is a long paragraph written to show how the line-height of an element is affected by our utilities. Classes are applied to the element itself or sometimes the parent element. These classes can be customized as needed with our utility API.</p>`} />

+## Overview
+
+Use height utilities to set the height of elements. Height utilities are generated from the utility API and include support for percentage values, intrinsic sizing keywords, and viewport units.
+
+## Relative height
+
+Set height relative to the parent element using percentage-based utilities. Includes support for `25%`, `50%`, `75%`, `100%`, and `auto` by default.
+
+<Example class="bd-example-flex" code={`<div style="height: 100px;">
+    <div class="h-25 d-inline-block" style="width: 120px;">Height 25%</div>
+    <div class="h-50 d-inline-block" style="width: 120px;">Height 50%</div>
+    <div class="h-75 d-inline-block" style="width: 120px;">Height 75%</div>
+    <div class="h-100 d-inline-block" style="width: 120px;">Height 100%</div>
+    <div class="h-auto d-inline-block" style="width: 120px;">Height auto</div>
+  </div>`} />
+
+## Intrinsic sizing
+
+Use intrinsic sizing keywords to set height based on content.
+
+<Example class="bd-example-flex" code={`<div style="height: 200px;">
+    <div class="h-min d-inline-block p-3" style="width: 120px;">Height min-content</div>
+    <div class="h-max d-inline-block p-3" style="width: 120px;">Height max-content</div>
+    <div class="h-fit d-inline-block p-3" style="width: 120px;">Height fit-content</div>
+  </div>`} />
+
+## Max height
+
+Set maximum height using `max-height` utilities.
+
+<Example class="bd-example-flex" code={`<div style="height: 100px;">
+    <div class="max-h-100" style="width: 100px; height: 200px;">Max-height 100%</div>
+  </div>`} />
+
+## Min height
+
+Set minimum height using `min-height` utilities.
+
+<Example class="bd-example-flex" code={`<div class="min-h-0 p-3" style="width: 200px;">
+    Min-height 0 (allows content to determine height)
+  </div>
+<div class="min-h-100 p-3" style="width: 200px;">Min-height 100%</div>`} />
+
+## Viewport height
+
+Set height relative to the viewport using viewport units.
+
+```html
+<div class="vh-100">Height 100vh</div>
+<div class="min-vh-100">Min-height 100vh</div>
+```
+
+<Callout>
+**Full viewport height sections!** Using `vh-100` makes an element take up the entire viewport height, which is useful for hero sections and full-screen layouts.

+## Overview
+
+Use `justify-content` utilities on flexbox containers to change the alignment of flex items on the main axis (the x-axis to start, y-axis if `flex-direction: column`). Choose from `start` (browser default), `end`, `center`, `between`, `around`, or `evenly`.

+## Overview
+
+Use `justify-items` utilities on CSS Grid containers to change the alignment of grid items along the inline (row) axis. This property controls how grid items are positioned horizontally within their grid areas.
+
+## Basic usage
+
+Use `justify-items` utilities to control the horizontal alignment of grid items. Choose from `start`, `end`, `center`, or `stretch` (browser default).

+
+## Overview
+
+Use margin utilities to control the outer space around elements. Margin utilities are built from a default Sass map ranging from `.25rem` to `3rem`.
+
+<Callout>
+**Using the CSS Grid layout module?** Consider using [the gap utility]([[docsref:/utilities/spacing#gap]]) instead.
+</Callout>
+
+## Notation
+
+Margin utilities that apply to all breakpoints, from `xs` to `xxl`, have no breakpoint abbreviation in them. This is because those classes are applied from `min-width: 0` and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.
+
+The classes are named using the format `{property}{sides}-{size}` for `xs` and `{property}{sides}-{breakpoint}-{size}` for `sm`, `md`, `lg`, `xl`, and `xxl`.
+
+Where *property* is:
+
+- `m` - for classes that set `margin`
+
+Where *sides* is one of:
+
+- `t` - for classes that set `margin-top`
+- `b` - for classes that set `margin-bottom`
+- `s` - (start) for classes that set `margin-left` in LTR, `margin-right` in RTL
+- `e` - (end) for classes that set `margin-right` in LTR, `margin-left` in RTL
+- `x` - for classes that set both `*-left` and `*-right`
+- `y` - for classes that set both `*-top` and `*-bottom`
+- blank - for classes that set a `margin` on all 4 sides of the element
+
+Where *size* is one of:
+
+- `0` - for classes that eliminate the `margin` by setting it to `0`
+- `1` - (by default) for classes that set the `margin` to `$spacer * .25`
+- `2` - (by default) for classes that set the `margin` to `$spacer * .5`
+- `3` - (by default) for classes that set the `margin` to `$spacer`
+- `4` - (by default) for classes that set the `margin` to `$spacer * 1.5`
+- `5` - (by default) for classes that set the `margin` to `$spacer * 3`
+- `auto` - for classes that set the `margin` to auto
+
+(You can add more sizes by adding entries to the `$spacers` Sass map variable.)
+
+## Examples
+
+Here are some representative examples of these classes:
+
+```scss
+.mt-0 {
+  margin-top: 0;
+}
+
+.ms-1 {
+  margin-left: ($spacer * .25);
+}
+
+.mx-2 {
+  margin-left: ($spacer * .5);
+  margin-right: ($spacer * .5);
+}
+
+.m-3 {
+  margin: $spacer;
+}
+```
+
+## Horizontal centering
+
+Bootstrap includes an `.mx-auto` class for horizontally centering fixed-width block level content—that is, content that has `display: block` and a `width` set—by setting the horizontal margins to `auto`.
+
+<Example showMarkup={false} code={`<div class="mx-auto p-2" style="width: 200px; background-color: rgba(var(--bd-violet-rgb),.15); border: rgba(var(--bd-violet-rgb),.3) solid 1px;">
+    Centered element
+  </div>`} />
+
+```html
+<div class="mx-auto p-2" style="width: 200px;">
+  Centered element
+</div>
+```
+
+## Negative margin
+
+When using `display: grid`, you can make use of negative margin utilities along the parent grid container. This can sometimes be helpful to match visual alignment of a child grid with the rest of your layout. Remember that [CSS Grid has a gap property]([[docsref:/utilities/spacing#gap]]) that might be an alternative solution.
+
+<Example showMarkup={false} code={`<div class="grid text-center" style="--bs-columns: 3; --bs-gap: .25rem;">
+    <div class="g-col-1">.g-col-1</div>
+    <div class="g-col-1">.g-col-1</div>
+    <div class="g-col-1">.g-col-1</div>
+  </div>`} />
+
+```html
+<div class="grid" style="--bs-columns: 3; --bs-gap: .25rem;">
+  <div class="g-col-1">.g-col-1</div>
+  <div class="g-col-1">.g-col-1</div>
+  <div class="g-col-1">.g-col-1</div>
+</div>
+```
+

+---
+
+## Overview
+
+Bootstrap provides `.pe-none` and `.pe-auto` classes to prevent or add element interactions through the `pointer-events` CSS property.
+
+## Basic usage
+
+<Example code={`<p><a href="#" class="pe-none" tabindex="-1" aria-disabled="true">This link</a> can not be clicked.</p>
+<p><a href="#" class="pe-auto">This link</a> can be clicked (this is default behavior).</p>
+<p class="pe-none"><a href="#" tabindex="-1" aria-disabled="true">This link</a> can not be clicked because the <code>pointer-events</code> property is inherited from its parent. However, <a href="#" class="pe-auto">this link</a> has a <code>pe-auto</code> class and can be clicked.</p>`} />
+
+## Important considerations
+
+The `.pe-none` class (and the `pointer-events` CSS property it sets) only prevents interactions with a pointer (mouse, stylus, touch). Links and controls with `.pe-none` are, by default, still focusable and actionable for keyboard users.
+
+To ensure that they are completely neutralized even for keyboard users, you may need to add further attributes such as:
+
+- `tabindex="-1"` (to prevent them from receiving keyboard focus)
+- `aria-disabled="true"` (to convey the fact they are effectively disabled to assistive technologies)
+- JavaScript to completely prevent them from being actionable
+
+## Better alternatives
+
+If possible, the simpler solution is:
+
+- **For form controls**: Add the `disabled` HTML attribute
+- **For links**: Remove the `href` attribute, making it a non-interactive anchor or placeholder link
+
+<Callout type="warning">
+**Accessibility warning:** Using `pointer-events: none` can create accessibility barriers. Always ensure that disabled elements are properly marked up with appropriate ARIA attributes and that keyboard users can't accidentally focus them.
+</Callout>
+
+## Use cases
+
+- **`.pe-none`** - Disable interactions on overlays, loading states, or temporarily disabled elements
+- **`.pe-auto`** - Re-enable interactions on child elements when parent has `pe-none`

-The classes are named using the format `{property}{sides}-{size}` for `xs` and `{property}{sides}-{breakpoint}-{size}` for `sm`, `md`, `lg`, `xl`, and `xxl`.

+## Overview
+
+Easily realign text to components with text alignment classes. For start, end, and center alignment, responsive classes are available that use the same viewport width breakpoints as the grid system.
+
+## Basic usage
+
+<Example code={`<p class="text-start">Start aligned text on all viewport sizes.</p>
+<p class="text-center">Center aligned text on all viewport sizes.</p>
+<p class="text-end">End aligned text on all viewport sizes.</p>
+
+<p class="text-sm-end">End aligned text on viewports sized SM (small) or wider.</p>
+<p class="text-md-end">End aligned text on viewports sized MD (medium) or wider.</p>
+<p class="text-lg-end">End aligned text on viewports sized LG (large) or wider.</p>
+<p class="text-xl-end">End aligned text on viewports sized XL (extra large) or wider.</p>
+<p class="text-xxl-end">End aligned text on viewports sized XXL (extra extra large) or wider.</p>`} />
+
+<Callout>
+Note that we don't provide utility classes for justified text. While, aesthetically, justified text might look more appealing, it does make word-spacing more random and therefore harder to read.
+</Callout>
+
+## Responsive
+
+Responsive variations also exist for `text-align`.
+
+<ul>
+{getData('breakpoints').map((breakpoint) => {
+  return (
+    <Fragment>
+      <li><code>.text{breakpoint.abbr}-start</code></li>
+      <li><code>.text{breakpoint.abbr}-center</code></li>

+
+Note how `.text-capitalize` only changes the first letter of each word, leaving the case of any other letters unaffected.
+
+## Reset color
+
+Reset a text or link's color with `.text-reset`, so that it inherits the color from its parent.

+Prevent long strings of text from breaking your components' layout by using `.text-break` to set `word-wrap: break-word` and `word-break: break-word`. We use `word-wrap` instead of the more common `overflow-wrap` for wider browser support, and add the deprecated `word-break: break-word` to avoid issues with flex containers.

+
+## Overview
+
+Use width utilities to set the width of elements. Width utilities are generated from the utility API and include support for percentage values, intrinsic sizing keywords, and viewport units.
+
+## Relative width
+
+Set width relative to the parent element using percentage-based utilities. Includes support for `25%`, `50%`, `75%`, `100%`, and `auto` by default.
+
+<Example class="bd-example-flex" code={`<div class="w-25 p-3">Width 25%</div>
+<div class="w-50 p-3">Width 50%</div>
+<div class="w-75 p-3">Width 75%</div>
+<div class="w-100 p-3">Width 100%</div>
+<div class="w-auto p-3">Width auto</div>`} />
+
+## Intrinsic sizing
+
+Use intrinsic sizing keywords to set width based on content.
+
+<Example class="bd-example-flex" code={`<div class="w-min p-3">Width min-content</div>
+<div class="w-max p-3">Width max-content</div>
+<div class="w-fit p-3">Width fit-content</div>`} />
+
+## Max width
+
+Set maximum width using `max-width` utilities.
+
+<Example class="bd-example-flex" code={`<div style="width: 50%;">
+    <div class="max-w-100" style="width: 200%;">Max-width 100%</div>
+  </div>`} />
+
+## Min width
+
+Set minimum width using `min-width` utilities.
+
+<Example class="bd-example-flex" code={`<div class="min-w-0 p-3" style="overflow: hidden;">
+    <div style="width: 200px;">This content is wider than the min-width: 0 container</div>
+  </div>
+<div class="min-w-100 p-3">Min-width 100%</div>`} />
+
+## Viewport width
+
+Set width relative to the viewport using viewport units.
+
+```html
+<div class="vw-100">Width 100vw</div>
+<div class="min-vw-100">Min-width 100vw</div>
+```
+
+<Callout type="warning">
+**Beware of the viewport width!** Using `vw-100` can cause horizontal scrollbars if the content is wider than the viewport, particularly on smaller screens.
