  <h1 id="tooltips" class="page-header">Tooltips <small>tooltip.js</small></h1>
  <p>Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.</p>
  <p>Tooltips with zero-length titles are never displayed.</p>

  <h2 id="tooltips-examples">Examples</h2>

  <div class="bs-callout bs-callout-danger" id="callout-tooltip-opt-in">
    <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>
    <p>One way to initialize all tooltips on a page would be to select them by their <code>data-toggle</code> attribute:</p>
{% highlight js %}
$(function () {
  $('[data-toggle="tooltip"]').tooltip()
})
{% endhighlight %}

  </div>

  <h2 id="tooltips-usage">Usage</h2>
  <p>The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.</p>
  <p>Trigger the tooltip via JavaScript:</p>
{% highlight js %}
$('#example').tooltip(options)
{% endhighlight %}

  <h3>Markup</h3>
  <p>The required markup for a tooltip is only a <code>data</code> attribute and <code>title</code> on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to <code>top</code> by the plugin).</p>

{% highlight html %}
<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>

<!-- Generated markup by the plugin -->
<div class="tooltip top" role="tooltip">
  <div class="tooltip-arrow"></div>
  <div class="tooltip-inner">
    Some tooltip text!
  </div>
</div>
{% endhighlight %}

  <div class="bs-callout bs-callout-warning" id="callout-tooltip-multiline">
    <h4>Multiple-line links</h4>
    <p>Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>
  </div>
  <div class="bs-callout bs-callout-warning" id="callout-tooltip-groups">
    <h4>Tooltips in button groups and input groups require special setting</h4>
    <p>When using tooltips 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 tooltip is triggered).</p>
  </div>
  <div class="bs-callout bs-callout-warning" id="callout-tooltip-hidden">
    <h4>Don't try to show tooltips on hidden elements</h4>
    <p>Invoking <code>$(...).tooltip('show')</code> when the target element is <code>display: none;</code> will cause the tooltip to be incorrectly positioned.</p>
  </div>
  <div class="bs-callout bs-callout-warning" id="callout-tooltip-accessibility">
    <h4>Accessible tooltips for keyboard and assistive technology users</h4>
    <p>For users navigating with a keyboard, and in particular users of assistive technologies, you should only add tooltips to keyboard-focusable elements such as links, form controls, or any arbitrary element with a <code>tabindex="0"</code> attribute.</p>
  </div>
  <div class="bs-callout bs-callout-info" id="callout-tooltip-disabled">
    <h4>Tooltips on disabled elements require wrapper elements</h4>
    <p>To add a tooltip to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code>&lt;div&gt;</code> and apply the tooltip to that <code>&lt;div&gt;</code> instead.</p>
  </div>

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

    <table class="table table-bordered table-striped js-options-table">

            <p>When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second. The <code>this</code> context is set to the tooltip instance.</p>

    <h4>Data attributes for individual tooltips</h4>
    <p>Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.</p>

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

  <h4><code>$().tooltip(options)</code></h4>
  <p>Attaches a tooltip handler to an element collection.</p>

  <h4><code>.tooltip('show')</code></h4>
  <p>Reveals an element's tooltip. <strong>Returns to the caller before the tooltip has actually been shown</strong> (i.e. before the <code>shown.bs.tooltip</code> event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.</p>
  {% highlight js %}$('#element').tooltip('show'){% endhighlight %}

  <h4><code>.tooltip('hide')</code></h4>
  <p>Hides an element's tooltip. <strong>Returns to the caller before the tooltip has actually been hidden</strong> (i.e. before the <code>hidden.bs.tooltip</code> event occurs). This is considered a "manual" triggering of the tooltip.</p>
  {% highlight js %}$('#element').tooltip('hide'){% endhighlight %}

  <h4><code>.tooltip('toggle')</code></h4>
  <p>Toggles an element's tooltip. <strong>Returns to the caller before the tooltip has actually been shown or hidden</strong> (i.e. before the <code>shown.bs.tooltip</code> or <code>hidden.bs.tooltip</code> event occurs). This is considered a "manual" triggering of the tooltip.</p>
  {% highlight js %}$('#element').tooltip('toggle'){% endhighlight %}

  <h4><code>.tooltip('destroy')</code></h4>
  <p>Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using <a href="#tooltips-options">the <code>selector</code> option</a>) cannot be individually destroyed on descendant trigger elements.</p>
