  <div class="bs-callout bs-callout-danger" id="callout-carousel-accessibility">
    <h4>Accessibility issue</h4>
    <p>The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.</p>
  </div>

  <div class="bs-callout bs-callout-warning" id="callout-carousel-transitions">
    <h4>Transition animations not supported in Internet Explorer 8 &amp; 9</h4>
    <p>Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 &amp; 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.</p>
  </div>

  <div class="bs-callout bs-callout-warning" id="callout-carousel-active">
    <h4>Initial active element required</h4>
    <p>The <code>.active</code> class needs to be added to one of the slides. Otherwise, the carousel will not be visible.</p>
  </div>

  <div class="bs-callout bs-callout-info" id="callout-carousel-without-glyphicons">
    <h4>Glyphicon icons not necessary</h4>
    <p>The <code>.glyphicon .glyphicon-chevron-left</code> and <code>.glyphicon .glyphicon-chevron-right</code> classes are not necessarily needed for the controls. Bootstrap provides <code>.icon-prev</code> and <code>.icon-next</code> as plain unicode alternatives.</p>
  </div>

  <h3>Optional captions</h3>
  <p>Add captions to your slides easily with the <code>.carousel-caption</code> element within any <code>.item</code>. Place just about any optional HTML within there and it will be automatically aligned and formatted.</p>

  <h2 id="carousel-usage">Usage</h2>

  <h3>Multiple carousels</h3>
  <p>Carousels require the use of an <code>id</code> on the outermost container (the <code>.carousel</code>) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's <code>id</code>, be sure to update the relevant controls.</p>

  <h3>Via data attributes</h3>
  <p>Use data attributes to easily control the position of the carousel. <code>data-slide</code> accepts the keywords <code>prev</code> or <code>next</code>, which alters the slide position relative to its current position. Alternatively, use <code>data-slide-to</code> to pass a raw slide index to the carousel <code>data-slide-to="2"</code>, which shifts the slide position to a particular index beginning with <code>0</code>.</p>
  <p>The <code>data-ride="carousel"</code> attribute is used to mark a carousel as animating starting at page load. <strong class="text-danger">It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.</strong></p>

  <h3>Via JavaScript</h3>
  <p>Call carousel manually with:</p>
{% highlight js %}
$('.carousel').carousel()
{% endhighlight %}

  <h3 id="carousel-options">Options</h3>
  <p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-interval=""</code>.</p>
  <div class="table-responsive">
    <table class="table table-bordered table-striped js-options-table">
      <thead>
       <tr>
         <th>Name</th>
         <th>type</th>
         <th>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 | null</td>
         <td>"hover"</td>
         <td>If set to <code>"hover"</code>, pauses the cycling of the carousel on <code>mouseenter</code> and resumes the cycling of the carousel on <code>mouseleave</code>. If set to <code>null</code>, hovering over the carousel won't pause it.</td>
       </tr>
       <tr>
         <td>wrap</td>
         <td>boolean</td>
         <td>true</td>

         <td>boolean</td>
         <td>true</td>
         <td>Whether the carousel should react to keyboard events.</td>
       </tr>
      </tbody>
    </table>
  </div><!-- /.table-responsive -->

  <h3 id="carousel-methods">Methods</h3>

  <h4><code>.carousel(options)</code></h4>
  <p>Initializes the carousel with an optional options <code>object</code> and starts cycling through items.</p>
{% highlight js %}
$('.carousel').carousel({
  interval: 2000
})
{% endhighlight %}

  <h4><code>.carousel('cycle')</code></h4>
  <p>Cycles through the carousel items from left to right.</p>

  <h4><code>.carousel('pause')</code></h4>
  <p>Stops the carousel from cycling through items.</p>


  <h4><code>.carousel(number)</code></h4>
  <p>Cycles the carousel to a particular frame (0 based, similar to an array).</p>

  <h4><code>.carousel('prev')</code></h4>
  <p>Cycles to the previous item.</p>

  <h4><code>.carousel('next')</code></h4>
  <p>Cycles to the next item.</p>

  <h3 id="carousel-events">Events</h3>
  <p>Bootstrap's carousel class exposes two events for hooking into carousel functionality.</p>
  <p>Both events have the following additional properties:</p>
  <ul>
    <li><code>direction</code>: The direction in which the carousel is sliding (either <code>"left"</code> or <code>"right"</code>).</li>
    <li><code>relatedTarget</code>: The DOM element that is being slid into place as the active item.</li>
  </ul>
  <p>All carousel events are fired at the carousel itself (i.e. at the <code>&lt;div class="carousel"&gt;</code>).</p>
  <div class="table-responsive">
    <table class="table table-bordered table-striped bs-events-table">
      <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>

$('#myCarousel').on('slide.bs.carousel', function () {
