A slideshow component for cycling through elements—images or slides of text—like a carousel. In browsers where the [Page Visibility API](http://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.). **Nested carousels are not supported.**
## Contents
* Will be replaced with the ToC, excluding the "Contents" header
#### Transition animations not supported in Internet Explorer 9
Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 9 doesn't support the necessary CSS properties. Thus, there are no slide transition animations when using that browser. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
{% endcallout %}
{% 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 %}
### Optional captions
Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`. Place just about any optional HTML within there and it will be automatically aligned and formatted.
The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.
{% endcallout %}
## Usage
### Multiple carousels
Carousels require the use of an `id` on the outermost container (the `.carousel`) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's `id`, be sure to update the relevant controls.
### 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=""`.
<divclass="table-responsive">
<tableclass="table table-bordered table-striped">
<thead>
<tr>
<thstyle="width: 100px;">Name</th>
<thstyle="width: 50px;">Type</th>
<thstyle="width: 50px;">Default</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>interval</td>
<td>number</td>
<td>5000</td>
<td>The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.</td>
</tr>
<tr>
<td>pause</td>
<td>string</td>
<td>"hover"</td>
<td>Pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave.</td>
</tr>
<tr>
<td>wrap</td>
<td>boolean</td>
<td>true</td>
<td>Whether the carousel should cycle continuously or have hard stops.</td>
</tr>
<tr>
<td>keyboard</td>
<td>boolean</td>
<td>true</td>
<td>Whether the carousel should react to keyboard events.</td>

</div>
### Methods
#### `.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).
#### `.carousel('prev')`
Cycles to the previous item.
#### `.carousel('next')`
Cycles to the next item.
### 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.
All carousel events are fired at the carousel itself (i.e. at the `<div class="carousel">`).
