  <p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p>

  <div class="bs-callout bs-callout-warning" id="callout-stacked-modals">
    <h4>Overlapping modals not supported</h4>
    <p>Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.</p>
  </div>
  <div class="bs-callout bs-callout-warning" id="callout-modal-markup-placement">
    <h4>Modal markup placement</h4>
    <p>Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.</p>
  </div>
  <div class="bs-callout bs-callout-warning" id="callout-modal-mobile-caveats">
    <h4>Mobile device caveats</h4>
    <p>There are some caveats regarding using modals on mobile devices. <a href="../getting-started/#support-fixed-position-keyboards">See our browser support docs</a> for details.</p>
  </div>

  <p><strong class="text-danger">Due to how HTML5 defines its semantics, the <code>autofocus</code> HTML attribute has no effect in Bootstrap modals.</strong> To achieve the same effect, use some custom JavaScript:</p>
  {% highlight js %}
  $('#myModal').on('shown.bs.modal', function () {
    $('#myInput').focus()
  })

  <h2 id="modals-usage">Usage</h2>
  <p>The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds <code>.modal-open</code> to the <code>&lt;body&gt;</code> to override default scrolling behavior and generates a <code>.modal-backdrop</code> to provide a click area for dismissing shown modals when clicking outside the modal.</p>

  <h3>Via data attributes</h3>
  <p>Activate a modal without writing JavaScript. Set <code>data-toggle="modal"</code> on a controller element, like a button, along with a <code>data-target="#foo"</code> or <code>href="#foo"</code> to target a specific modal to toggle.</p>
{% highlight html %}
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
{% endhighlight %}

  <h3>Via JavaScript</h3>
  <p>Call a modal with id <code>myModal</code> with a single line of JavaScript:</p>
  {% highlight js %}$('#myModal').modal(options){% endhighlight %}

  <h3 id="modals-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-backdrop=""</code>.</p>

If you're using the data-api, you may alternatively use the <code>href</code> attribute to specify the remote source. An example of this is shown below:</p>
