-## 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.).
-
-{% include callout-info-prefersreducedmotion.md %}
-
-Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards.
-
-Lastly, if you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/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.
-
-**The `.active` class needs to be added to one of the slides** otherwise the carousel will not be visible. Also be sure to set a unique id on the `.carousel` for optional controls, especially if you're using multiple carousels on a single page. Control and indicator elements must have a `data-target` attribute (or `href` for links) that matches the id of the `.carousel` element.
-
-### Slides only
-
-Here's a carousel with slides only. Note the presence of the `.d-block` and `.w-100` on carousel images to prevent browser default image alignment.
-
-{% capture example %}
-<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
- <div class="carousel-inner">
- <div class="carousel-item active">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %}

- </div>
- </div>
-</div>
-{% endcapture %}
-{% include example.html content=example %}
-
-### With controls
-
-Adding in the previous and next controls:
-
-{% capture example %}
-<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
- <div class="carousel-inner">
- <div class="carousel-item active">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="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>
-{% endcapture %}
-{% include example.html content=example %}
-
-### With indicators
-
-You can also add the indicators to the carousel, alongside the controls, too.
-
-{% capture example %}
-<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">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="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>
-{% endcapture %}
-{% include example.html content=example %}
-
-### 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`.
-
-{% capture example %}
-<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>
- </ol>
- <div class="carousel-inner">
- <div class="carousel-item active">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %}
- <div class="carousel-caption d-none d-md-block">
- <h5>First slide label</h5>
- <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
- </div>
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %}
- <div class="carousel-caption d-none d-md-block">
- <h5>Second slide label</h5>
- <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
- </div>
- </div>
- <div class="carousel-item">

- <div class="carousel-caption d-none d-md-block">
- <h5>Third slide label</h5>
- <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
- </div>
- </div>
- </div>
- <a class="carousel-control-prev" href="#carouselExampleCaptions" role="button" data-slide="prev">
- <span class="carousel-control-prev-icon" aria-hidden="true"></span>

- </a>
- <a class="carousel-control-next" href="#carouselExampleCaptions" role="button" data-slide="next">

- <span class="sr-only">Next</span>
- </a>
- </div>
-</div>
-{% endcapture %}
-{% include example.html content=example %}
-
-### Crossfade
-
-Add `.carousel-fade` to your carousel to animate slides with a fade transition instead of a slide.
-
-{% capture example %}
-<div id="carouselExampleFade" class="carousel slide carousel-fade" data-ride="carousel">
- <div class="carousel-inner">
- <div class="carousel-item active">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" %}
- </div>
- </div>
- <a class="carousel-control-prev" href="#carouselExampleFade" 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="#carouselExampleFade" role="button" data-slide="next">
- <span class="carousel-control-next-icon" aria-hidden="true"></span>
- <span class="sr-only">Next</span>
- </a>
-</div>
-{% endcapture %}
-{% include example.html content=example %}
-
-### Individual `.carousel-item` interval
-
-Add `data-interval=""` to a `.carousel-item` to change the amount of time to delay between automatically cycling to the next item.
-
-{% capture example %}
-<div id="carouselExampleInterval" class="carousel slide" data-ride="carousel">
- <div class="carousel-inner">
- <div class="carousel-item active" data-interval="10000">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %}
- </div>
- <div class="carousel-item" data-interval="2000">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %}
- </div>
- <div class="carousel-item">
- {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" %}
- </div>
- </div>
- <a class="carousel-control-prev" href="#carouselExampleInterval" 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="#carouselExampleInterval" role="button" data-slide="next">
- <span class="carousel-control-next-icon" aria-hidden="true"></span>
- <span class="sr-only">Next</span>
- </a>
-</div>
-{% endcapture %}
-{% include example.html content=example %}

-## 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. If you don't use `data-ride="carousel"` to initialize your carousel, you have to initialize it yourself. **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=""`.

-### Methods
-
-{% include callout-danger-async-methods.md %}
-
-#### `.carousel(options)`
-
-Initializes the carousel with an optional options `object` and starts cycling through items.
-
-{% highlight js %}
-$('.carousel').carousel({
- interval: 2000
-})
-{% endhighlight %}
-
-#### `.carousel('cycle')`
-
-Cycles through the carousel items from left to right.
-
-#### `.carousel('pause')`
-
-Stops the carousel from cycling through items.
-
-#### `.carousel(number)`
-
-Cycles the carousel to a particular frame (0 based, similar to an array). **Returns to the caller before the target item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
-
-#### `.carousel('prev')`
-
-Cycles to the previous item. **Returns to the caller before the previous item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
-
-#### `.carousel('next')`
-
-Cycles to the next item. **Returns to the caller before the next item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
-
-#### `.carousel('dispose')`
-
-Destroys an element's carousel.
-
-### Events
-
-Bootstrap's carousel class exposes two events for hooking into carousel functionality. Both events have the following additional properties:
-
-- `direction`: The direction in which the carousel is sliding (either `"left"` or `"right"`).
-- `relatedTarget`: The DOM element that is being slid into place as the active item.
-- `from`: The index of the current item
-- `to`: The index of the next item
-
-All carousel events are fired at the carousel itself (i.e. at the `<div class="carousel">`).
-
-<table class="table table-bordered table-striped">
- <thead>
- <tr>
- <th style="width: 150px;">Event Type</th>
- <th>Description</th>
- </tr>
- </thead>
- <tbody>
- <tr>
- <td>slide.bs.carousel</td>
- <td>This event fires immediately when the <code>slide</code> instance method is invoked.</td>
- </tr>
- <tr>
- <td>slid.bs.carousel</td>
- <td>This event is fired when the carousel has completed its slide transition.</td>
- </tr>
- </tbody>
-</table>
-
-{% highlight js %}
-$('#myCarousel').on('slide.bs.carousel', function () {
- // do something...
-})
-{% endhighlight %}
-
-### Change transition duration
-
-The transition duration of `.carousel-item` can be changed with the `$carousel-transition` Sass variable before compiling or custom styles if you're using the compiled CSS. If multiple transitions are applied, make sure the transform transition is defined first (eg. `transition: transform 2s ease, opacity .5s ease-out`).
