+
+Have a need for Bootstrap's brand resources? Great! We have only a few guidelines we follow, and in turn ask you to follow as well. These guidelines were inspired by MailChimp's [Brand Assets](https://mailchimp.com/about/brand-assets/).
+
+## Mark and logo
+
+Use either the Bootstrap mark (a capital **B**) or the standard logo (just **Bootstrap**). It should always appear in San Francisco Display Semibold. **Do not use the Twitter bird** in association with Bootstrap.
+
+<div class="bd-brand-logos">

+    <span class="h1">Bootstrap</span>
+  </div>

+## Download mark
+
+Download the Bootstrap mark in one of three styles, each available as an SVG file. Right click, Save as.

+
+## Name
+
+The project and framework should always be referred to as **Bootstrap**. No Twitter before it, no capital _s_, and no abbreviations except for one, a capital **B**.
+
+<div class="bd-brand-logos">
+  <div class="bd-brand-item">

+    <strong class="text-warning">Wrong</strong>
+  </div>
+</div>
+
+## Colors
+
+Our docs and branding use a handful of primary colors to differentiate what *is* Bootstrap from what *is in* Bootstrap. In other words, if it's purple, it's representative of Bootstrap.

+description: A brief overview of the history of Bootstrap.
+redirect_from:
+ - /about/
+---
+
+Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.
+
+Bootstrap was created at Twitter in mid-2010 by [@mdo](https://twitter.com/mdo) and [@fat](https://twitter.com/fat). Prior to being an open-sourced framework, Bootstrap was known as _Twitter Blueprint_. A few months into development, Twitter held its [first Hack Week](https://blog.twitter.com/2010/hack-week) and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.
+
+Originally [released](https://blog.twitter.com/2011/bootstrap-from-twitter) on [<time datetime="2011-08-19 11:25">Friday, August 19, 2011</time>](https://twitter.com/mdo/statuses/104620039650557952), we've since had over [twenty releases](https://github.com/twbs/bootstrap/releases), including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.

+- If you're building our JS from source, it [requires `util.js`]({{ site.baseurl }}/docs/getting-started/javascript/#util). The compiled version includes this.
 - Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
 - On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices.
-- To animate alerts when dismissing them, be sure to add the `.fade` and `.in` classes.

+description: Documentation and examples for badges, our small count and labeling component.

+## Example
+
+Badges scale to match the size of the immediate parent element by using relative font sizing and `em` units.
+
+<div class="bd-example">
+<div class="h1">Example heading <span class="badge badge-secondary">New</span></div>
+<div class="h2">Example heading <span class="badge badge-secondary">New</span></div>

+<h2>Example heading <span class="badge badge-secondary">New</span></h2>
+<h3>Example heading <span class="badge badge-secondary">New</span></h3>
+<h4>Example heading <span class="badge badge-secondary">New</span></h4>
+<h5>Example heading <span class="badge badge-secondary">New</span></h5>
+<h6>Example heading <span class="badge badge-secondary">New</span></h6>
+{% endhighlight %}
+
+Badges can be used as part of links or buttons to provide a counter.
+
+{% example html %}
+<button class="btn btn-primary">
+  Notifications <span class="badge badge-light">4</span>
+</button>
+{% endexample %}
+
+Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.
+
+Unless the context is clear (as with the "Notifications" example, where it is understood that the "4" is the number of notifications), consider including additional context with a visually hidden piece of additional text.
+
+{% example html %}
+<button class="btn btn-primary">
+  Profile <span class="badge badge-light">9</span>
+  <span class="sr-only">unread messages</span>
+</button>
+{% endexample %}
+
+## Contextual variations
+
+Add any of the below mentioned modifier classes to change the appearance of a badge.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+<span class="badge badge-{{ color.name }}">{{ color.name | capitalize }}</span>{% endfor %}
+{% endexample %}
+
+{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
+{{ callout-include | markdownify }}
+
+## Pill badges
+
+Use the `.badge-pill` modifier class to make badges more rounded (with a larger `border-radius` and additional horizontal `padding`). Useful if you miss the badges from v3.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+<span class="badge badge-pill badge-{{ color.name }}">{{ color.name | capitalize }}</span>{% endfor %}
+{% endexample %}
+
+## Links
+
+Using the `.badge` classes with the `<a>` element quickly provide _actionable_ badges with hover and focus states.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+<a href="#" class="badge badge-{{ color.name }}">{{ color.name | capitalize }}</a>{% endfor %}

+title: Cards
+description: Bootstrap's cards provide a flexible and extensible content container with multiple variants and options.
+group: components
+toc: true
+---
+
+## About
+
+A **card** is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options.
+
+If you're familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.
+
+## Example
+
+Cards are built with as little markup and styles as possible, but still manage to deliver a ton of control and customization. Built with flexbox, they offer easy alignment and mix well with other Bootstrap components.
+
+Below is an example of a basic card with mixed content and a fixed width. Cards have no fixed width to start, so they'll naturally fill the full width of its parent element. This is easily customized with our various [sizing options](#sizing).
+
+{% example html %}
+<div class="card" style="width: 20rem;">
+  <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+  <div class="card-body">
+    <h4 class="card-title">Card title</h4>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{% endexample %}
+
+## Content types
+
+Cards support a wide variety of content, including images, text, list groups, links, and more. Below are examples of what's supported.
+
+### Blocks
+
+The building block of a card is the `.card-body`. Use it whenever you need a padded section within a card.
+
+{% example html %}
+<div class="card">
+  <div class="card-body">
+    This is some text within a card block.
+  </div>
+</div>
+{% endexample %}
+
+### Titles, text, and links
+
+Card titles are used by adding `.card-title` to a `<h*>` tag. In the same way, links are added and placed next to each other by adding `.card-link` to  a `<a>` tag.
+
+Subtitles are used by adding a `.card-subtitle` to a `<h*>` tag. If the `.card-title` and the `.card-subtitle` items are placed in a `.card-body` item, the card title and subtitle are aligned nicely.
+
+{% example html %}
+<div class="card" style="width: 20rem;">
+  <div class="card-body">
+    <h4 class="card-title">Card title</h4>
+    <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+    <a href="#" class="card-link">Card link</a>
+    <a href="#" class="card-link">Another link</a>
+  </div>
+</div>
+{% endexample %}
+
+### Images
+
+`.card-img-top` places an image to the top of the card. With `.card-text`, text can be added to the card. Text within `.card-text` can also be styled with the standard HTML tags.
+
+{% example html %}
+<div class="card" style="width: 20rem;">
+  <img class="card-img-top" data-src="holder.js/100px180/?text=Image cap" alt="Card image cap">
+  <div class="card-body">
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>
+{% endexample %}
+
+### List groups
+
+Create lists of content in a card with a flush list group.
+
+{% example html %}
+<div class="card" style="width: 20rem;">
+  <ul class="list-group list-group-flush">
+    <li class="list-group-item">Cras justo odio</li>
+    <li class="list-group-item">Dapibus ac facilisis in</li>
+    <li class="list-group-item">Vestibulum at eros</li>
+  </ul>
+</div>
+{% endexample %}

+
+## Sizing
+
+Cards assume no specific `width` to start, so they'll be 100% wide unless otherwise stated. You can change this as needed with custom CSS, grid classes, grid Sass mixins, or utilities.
+
+### Using grid markup
+
+Using the grid, wrap cards in columns and rows as needed.
+
+{% example html %}
+<div class="row">
+  <div class="col-sm-6">
+    <div class="card">
+      <div class="card-body">
+        <h4 class="card-title">Special title treatment</h4>
+        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+        <a href="#" class="btn btn-primary">Go somewhere</a>
+      </div>
+    </div>
+  </div>
+  <div class="col-sm-6">
+    <div class="card">
+      <div class="card-body">
+        <h4 class="card-title">Special title treatment</h4>
+        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+        <a href="#" class="btn btn-primary">Go somewhere</a>
+      </div>
+    </div>
+  </div>
+</div>
+{% endexample %}
+
+### Using utilities
+
+Use our handful of [available sizing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/sizing/) to quickly set a card's width.
+
+{% example html %}
+<div class="card w-75">
+  <div class="card-body">
+    <h4 class="card-title">Card title</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Button</a>
+  </div>
+</div>
+
+<div class="card w-50">
+  <div class="card-body">
+    <h4 class="card-title">Card title</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Button</a>
+  </div>
+</div>
+{% endexample %}
+
+### Using custom CSS
+
+Use custom CSS in your stylesheets or as inline styles to set a width.
+
+{% example html %}
+<div class="card" style="width: 20rem;">
+  <div class="card-body">
+    <h4 class="card-title">Special title treatment</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{% endexample %}
+
+## Text alignment
+
+You can quickly change the text alignment of any card—in its entirety or specific parts—with our [text align classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/#text-alignment).
+
+{% example html %}
+<div class="card" style="width: 20rem;">
+  <div class="card-body">
+    <h4 class="card-title">Special title treatment</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+
+<div class="card text-center" style="width: 20rem;">
+  <div class="card-body">
+    <h4 class="card-title">Special title treatment</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+
+<div class="card text-right" style="width: 20rem;">
+  <div class="card-body">
+    <h4 class="card-title">Special title treatment</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{% endexample %}
+
+## Navigation
+
+Add some navigation to a card's header (or block) with Bootstrap's [nav components]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/navs/).
+
+{% example html %}
+<div class="card text-center">
+  <div class="card-header">
+    <ul class="nav nav-tabs card-header-tabs">
+      <li class="nav-item">
+        <a class="nav-link active" href="#">Active</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#">Disabled</a>
+      </li>
+    </ul>
+  </div>
+  <div class="card-body">
+    <h4 class="card-title">Special title treatment</h4>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{% endexample %}
+
+{% example html %}
+<div class="card text-center">
+  <div class="card-header">
+    <ul class="nav nav-pills card-header-pills">
+      <li class="nav-item">
+        <a class="nav-link active" href="#">Active</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item">

+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{% endexample %}
+
+## Images
+
+Cards include a few options for working with images. Choose from appending "image caps" at either end of a card, overlaying images with card content, or simply embedding the image in a card.
+
+### Image caps
+
+Similar to headers and footers, cards can include top and bottom "image caps"—images at the top or bottom of a card.
+
+{% example html %}
+<div class="card mb-3">
+  <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+  <div class="card-body">
+    <h4 class="card-title">Card title</h4>
+    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+  </div>
+</div>
+<div class="card">
+  <div class="card-body">
+    <h4 class="card-title">Card title</h4>
+    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+  </div>
+  <img class="card-img-bottom" data-src="holder.js/100px180/" alt="Card image cap">
+</div>
+{% endexample %}
+
+### Image overlays
+
+Turn an image into a card background and overlay your card's text. Depending on the image, you may or may not need additional styles or utilities.
+
+{% example html %}
+<div class="card bg-dark text-white">
+  <img class="card-img" data-src="holder.js/100px270/#55595c:#373a3c/text:Card image" alt="Card image">
+  <div class="card-img-overlay">
+    <h4 class="card-title">Card title</h4>
+    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+    <p class="card-text">Last updated 3 mins ago</p>
+  </div>
+</div>
+{% endexample %}
+
+## Card styles
+
+Cards include various options for customizing their backgrounds, borders, and color.
+
+### Background and color
+
+Use [text and background utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/) to change the appearance of a card.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+<div class="card{% unless color.name == "light" %} text-white{% endunless %} bg-{{ color.name }} mb-3" style="max-width: 20rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body">
+    <h4 class="card-title">{{ color.name | capitalize }} card title</h4>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>{% endfor %}
+{% endexample %}
+
+{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
+{{ callout-include | markdownify }}
+
+### Border
+
+Use [border utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/) to change just the `border-color` of a card. Note that you can put `.text-{color}` classes on the parent `.card` or a subset of the card's contents as shown below.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+<div class="card border-{{ color.name }} mb-3" style="max-width: 20rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body{% unless color.name == "light" %} text-{{ color.name }}{% endunless %}">
+    <h4 class="card-title">{{ color.name | capitalize }} card title</h4>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>{% endfor %}
+{% endexample %}
+
+### Mixins utilities
+
+You can also change the borders on the card header and footer as needed, and even remove their `background-color` with `.bg-transparent`.
+
+{% example html %}
+<div class="card border-success mb-3" style="max-width: 20rem;">
+  <div class="card-header bg-transparent border-success">Header</div>
+  <div class="card-body text-success">
+    <h4 class="card-title">Success card title</h4>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+  <div class="card-footer bg-transparent border-success">Footer</div>
+</div>
+{% endexample %}
+
+## Card layout
+
+In addition to styling the content within cards, Bootstrap includes a few options for laying out series of cards. For the time being, **these layout options are not yet responsive**.
+
+### Card groups
+
+Use card groups to render cards as a single, attached element with equal width and height columns. Card groups use `display: flex;` to achieve their uniform sizing.
+
+{% example html %}
+<div class="card-group">
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+    <div class="card-body">
+      <h4 class="card-title">Card title</h4>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+    </div>
+  </div>
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+    <div class="card-body">
+      <h4 class="card-title">Card title</h4>
+      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
+      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+    </div>
+  </div>
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+    <div class="card-body">
+      <h4 class="card-title">Card title</h4>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
+      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+    </div>
+  </div>
+</div>
+{% endexample %}
+
+When using card groups with footers, their content will automatically line up.
+
+{% example html %}
+<div class="card-group">
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+    <div class="card-body">
+      <h4 class="card-title">Card title</h4>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+    </div>
+    <div class="card-footer">
+      <small class="text-muted">Last updated 3 mins ago</small>
+    </div>
+  </div>
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
+    <div class="card-body">
+      <h4 class="card-title">Card title</h4>
+      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
+    </div>
+    <div class="card-footer">

+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
+    </div>
+    <div class="card-footer">
+      <small class="text-muted">Last updated 3 mins ago</small>
+    </div>
+  </div>
+</div>
+{% endexample %}
+
+### Card decks
+
+Need a set of equal width and height cards that aren't attached to one another? Use card decks.
+
+{% example html %}
+<div class="card-deck">
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px200/" alt="Card image cap">
+    <div class="card-body">

+  <div class="card">

+{% endexample %}
+
+Just like with card groups, card footers in decks will automatically line up.

+
+### Card columns
+
+Cards can be organized into [Masonry](http://masonry.desandro.com)-like columns with just CSS by wrapping them in `.card-columns`. Cards are built with CSS `column` properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to right.
+
+**Heads up!** Your mileage with card columns may vary. To prevent cards breaking across columns, we must set them to `display: inline-block` as `column-break-inside: avoid` isn't a bulletproof solution yet.
+
+{% example html %}
+<div class="card-columns">
+  <div class="card">
+    <img class="card-img-top" data-src="holder.js/100px160/" alt="Card image cap">

+title: Carousel
+description: A slideshow component for cycling through elements—images or slides of text—like a carousel.
+group: components
+toc: true
+---
+
+## How it works
+
+The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms and a bit of JavaScript. It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators.
+
+In browsers where the [Page Visibility API](https://www.w3.org/TR/page-visibility/) is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.).
+
+Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards.
+
+Lastly, if you're building our JS from source, it [requires `util.js`]({{ site.baseurl }}/docs/getting-started/javascript/#util).
+
+## Example
+
+Carousels don't automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they're not explicitly required. Add and customize as you see fit.
+
+Be sure to set a unique id on the `.carousel` for optional controls, especially if you're using multiple carousels on a single page.
+
+### Slides only
+
+Here's a carousel with slides only. Note the presence of the `.d-block` and `.img-fluid` on carousel images to prevent browser default image alignment.
+
+{% example html %}
+<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
+    </div>
+    <div class="carousel-item">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
+    </div>
+    <div class="carousel-item">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
+    </div>
+  </div>
+</div>
+{% endexample %}
+
+### With controls
+
+Adding in the previous and next controls:
+
+{% example html %}
+<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
+    </div>
+    <div class="carousel-item">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
+    </div>
+    <div class="carousel-item">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{% endexample %}
+
+### With indicators
+
+You can also add the indicators to the carousel, alongside the controls, too.
+
+{% example html %}
+<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
+  <ol class="carousel-indicators">
+    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
+    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
+    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
+  </ol>
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
+    </div>
+    <div class="carousel-item">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
+    </div>
+    <div class="carousel-item">
+      <img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{% endexample %}
+
+{% callout warning %}
+#### Initial active element required
+
+The `.active` class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
+{% endcallout %}
+
+### With captions
+
+Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`. They can be easily hidden on smaller viewports, as shown below, with optional [display utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/). We hide them initially with `.d-none` and bring them back on medium-sized devices with `.d-md-block`.

+<div class="bd-example">
+  <div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel">
+    <ol class="carousel-indicators">
+      <li data-target="#carouselExampleCaptions" data-slide-to="0" class="active"></li>
+      <li data-target="#carouselExampleCaptions" data-slide-to="1"></li>
+      <li data-target="#carouselExampleCaptions" data-slide-to="2"></li>

+
+## Usage
+
+### Via data attributes
+
+Use data attributes to easily control the position of the carousel. `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`.
+
+The `data-ride="carousel"` attribute is used to mark a carousel as animating starting at page load. **It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.**
+
+### Via JavaScript
+
+Call carousel manually with:
+
+{% highlight js %}
+$('.carousel').carousel()
+{% endhighlight %}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.
+
+<table class="table table-bordered table-striped table-responsive">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 50px;">Type</th>
+      <th style="width: 50px;">Default</th>

+      <p>On touch-enabled devices, when set to <code>"hover"</code>, cycling will pause on <code>touchend</code> (once the user finished interacting with the carousel) for two intervals, before automatically resuming. Note that this is in addition to the above mouse behavior.</p></td>

+
+### Methods
+
+{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
+{{ callout-include | markdownify }}
+
+#### `.carousel(options)`
+
+Initializes the carousel with an optional options `object` and starts cycling through items.
+
+{% highlight js %}
+$('.carousel').carousel({
+  interval: 2000
+})
+{% endhighlight %}
+
+#### `.carousel('cycle')`
+
+Cycles through the carousel items from left to right.
+
+#### `.carousel('pause')`
+
+Stops the carousel from cycling through items.
+
+#### `.carousel(number)`
+
+Cycles the carousel to a particular frame (0 based, similar to an array). **Returns to the caller before the target item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+#### `.carousel('prev')`
+
+Cycles to the previous item. **Returns to the caller before the previous item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+#### `.carousel('next')`
+
+Cycles to the next item. **Returns to the caller before the next item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+### Events
+
+Bootstrap's carousel class exposes two events for hooking into carousel functionality. Both events have the following additional properties:
+
+- `direction`: The direction in which the carousel is sliding (either `"left"` or `"right"`).
+- `relatedTarget`: The DOM element that is being slid into place as the active item.
+- `from`: The index of the current item
+- `to`: The index of the next item
+
+All carousel events are fired at the carousel itself (i.e. at the `<div class="carousel">`).
+
+<table class="table table-bordered table-striped table-responsive">
+  <thead>
+    <tr>
+      <th style="width: 150px;">Event Type</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>slide.bs.carousel</td>
+      <td>This event fires immediately when the <code>slide</code> instance method is invoked.</td>
+    </tr>
+    <tr>
+      <td>slid.bs.carousel</td>
+      <td>This event is fired when the carousel has completed its slide transition.</td>
+    </tr>
+  </tbody>
+</table>
+
+{% highlight js %}
+$('#myCarousel').on('slide.bs.carousel', function () {
+  // do something…
+})
+{% endhighlight %}
