  <h2 id="popovers-examples">Examples</h2>
  <p>Add small overlays of content, like those on the iPad, to any element for housing secondary information.</p>

  <div class="bs-callout bs-callout-danger">
    <h4>Plugin dependency</h4>
    <p>Popovers require the <a href="#tooltips">tooltip plugin</a> to be included in your version of Bootstrap.</p>
  </div>
  <div class="bs-callout bs-callout-danger">
    <h4>Opt-in functionality</h4>
    <p>For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning <strong>you must initialize them yourself</strong>.</p>
  </div>
  <div class="bs-callout bs-callout-warning">
    <h4>Popovers in button groups and input groups require special setting</h4>
    <p>When using popovers on elements within a <code>.btn-group</code> or an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).</p>
  </div>
  <div class="bs-callout bs-callout-warning">
    <h4>Don't try to show popovers on hidden elements</h4>
    <p>Invoking <code>$(...).popover('show')</code> when the target element is <code>display: none;</code> will cause the popover to be incorrectly positioned.</p>
  </div>
  <div class="bs-callout bs-callout-info">
    <h4>Popovers on disabled elements require wrapper elements</h4>
    <p>To add a popover to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code>&lt;div&gt;</code> and apply the popover to that <code>&lt;div&gt;</code> instead.</p>
  </div>

  <h3>Static popover</h3>
  <p>Four options are available: top, right, bottom, and left aligned.</p>
  <div class="bs-example bs-example-popover">
    <div class="popover top">
      <div class="arrow"></div>
      <h3 class="popover-title">Popover top</h3>
      <div class="popover-content">
        <p>Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>
      </div>
    </div>

    <div class="popover right">
      <div class="arrow"></div>
      <h3 class="popover-title">Popover right</h3>
      <div class="popover-content">
        <p>Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>
      </div>

      <h3 class="popover-title">Popover bottom</h3>

      <div class="popover-content">
        <p>Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>

    </div>

    <div class="popover left">
      <div class="arrow"></div>

      <div class="popover-content">

  <h4>Dismiss on next click</h4>
  <p>Use the <code>focus</code> trigger to dismiss popovers on the next click that the user makes.</p>

{% endhighlight %}
{% highlight js %}
$('.popover-dismiss').popover({
  trigger: 'focus'
})
{% endhighlight %}

  <div class="bs-callout bs-callout-warning">
    <h4>Multiple-line links</h4>
    <p>Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>
  </div>


  <h2 id="popovers-usage">Usage</h2>
  <p>Enable popovers via JavaScript:</p>
  {% highlight js %}$('#example').popover(options){% endhighlight %}

  <h3>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-animation=""</code>.</p>
