        <!-- Overview
        ================================================== -->
        <section id="overview">
          <div class="page-header">
            <h1>JavaScript in Bootstrap</h1>
          </div>

          <h3>Individual or compiled</h3>
          <p>Plugins can be included individually (though some have required dependencies), or all at once. Both <strong>bootstrap.js</strong> and <strong>bootstrap.min.js</strong> contain all plugins in a single file.</p>

          <h3>Data attributes</h3>
          <p>You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first class API and should be your first consideration when using a plugin.</p>

          <p>That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the body namespaced with `'data-api'`. This looks like this:
          <pre class="prettyprint linenums">$('body').off('.data-api')</pre>

          <p>Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:</p>
          <pre class="prettyprint linenums">$('body').off('.alert.data-api')</pre>

          <h3>Programmatic API</h3>
          <p>We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.</p>
          <pre class="prettyprint linenums">$(".btn.danger").button("toggle").addClass("fat")</pre>
          <p>All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):</p>
<pre class="prettyprint linenums">
$("#myModal").modal()                       // initialized with defaults
$("#myModal").modal({ keyboard: false })   // initialized with no keyboard
$("#myModal").modal('show')                // initializes and invokes show immediately</p>
</pre>
          <p>Each plugin also exposes its raw constructor on a `Constructor` property: <code>$.fn.popover.Constructor</code>. If you'd like to get a particular plugin instance, retrieve it directly from an element: <code>$('[rel=popover]').data('popover')</code>.</p>

          <h3>No Conflict</h3>
          <p>Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances,  namespace collisions can occasionally occur. If this happens, you may call <code>.noConflict</code> on the plugin you wish to revert the value of.</p>

<pre class="prettyprint linenums">
var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton            // give $().bootstrapBtn the bootstrap functionality
</pre>

          <h3>Events</h3>
          <p>Bootstrap provides custom events for most plugin's unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. <code>show</code>) is triggered at the start of an event, and its past participle form (ex. <code>shown</code>) is trigger on the completion of an action.</p>
          <p>All infinitive events provide preventDefault functionality. This provides the ability to stop the execution of an action before it starts.</p>
<pre class="prettyprint linenums">
$('#myModal').on('show', function (e) {
    if (!data) return e.preventDefault() // stops modal from being shown
})
</pre>
        </section>


        <!-- Transitions
        ================================================== -->
        <section id="transitions">
          <div class="page-header">
            <h1>Transitions <small>bootstrap-transition.js</small></h1>
          </div>
          <h3>About transitions</h3>
          <p>For simple transition effects, include bootstrap-transition.js once alongside the other JS files. If you're using the compiled (or minified) bootstrap.js, there is no need to include this&mdash;it's already there.</p>
          <h3>Use cases</h3>
          <p>A few examples of the transition plugin:</p>
          <ul>
            <li>Sliding or fading in modals</li>
            <li>Fading out tabs</li>
            <li>Fading out alerts</li>
            <li>Sliding carousel panes</li>
          </ul>

        </section>


        <!-- Modal
        ================================================== -->
        <section id="modals">
          <div class="page-header">
            <h1>Modals <small>bootstrap-modal.js</small></h1>
          </div>


          <h2>Examples</h2>
          <p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p>

          <h3>Static example</h3>
          <p>A rendered modal with header, body, and set of actions in the footer.</p>
          <div class="bs-docs-example" style="background-color: #f5f5f5;">

              <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h3>Modal header</h3>
              </div>
              <div class="modal-body">
                <p>One fine body&hellip;</p>
              </div>
              <div class="modal-footer">
                <a href="#" class="btn">Close</a>
                <a href="#" class="btn btn-primary">Save changes</a>
              </div>
            </div>
          </div>
<pre class="prettyprint linenums">
&lt;div class="modal hide fade"&gt;
  &lt;div class="modal-header"&gt;
    &lt;button type="button" class="close" data-dismiss="modal" aria-hidden="true"&gt;&amp;times;&lt;/button&gt;
    &lt;h3&gt;Modal header&lt;/h3&gt;
  &lt;/div&gt;
  &lt;div class="modal-body"&gt;
    &lt;p&gt;One fine body&hellip;&lt;/p&gt;
  &lt;/div&gt;
  &lt;div class="modal-footer"&gt;
    &lt;a href="#" class="btn"&gt;Close&lt;/a&gt;
    &lt;a href="#" class="btn btn-primary"&gt;Save changes&lt;/a&gt;
  &lt;/div&gt;
&lt;/div&gt;

          <h2>Usage</h2>

          <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>
          <pre class="prettyprint linenums">&lt;button type="button" data-toggle="modal" data-target="#myModal"&gt;Launch modal&lt;/button&gt;</pre>

          <h3>Via JavaScript</h3>
          <p>Call a modal with id <code>myModal</code> with a single line of JavaScript:</p>
          <pre class="prettyprint linenums">$('#myModal').modal(options)</pre>

          <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-backdrop=""</code>.</p>
          <table class="table table-bordered table-striped">
            <thead>
             <tr>

               <td>false</td>
               <td><p>If a remote url is provided, content will be loaded via jQuery's <code>load</code> method and injected into the <code>.modal-body</code>. If you're using the data api, you may alternatively use the <code>href</code> tag to specify the remote source. An example of this is shown below:</p>
              <pre class="prettyprint linenums"><code>&lt;a data-toggle="modal" href="remote.html" data-target="#modal"&gt;click me&lt;/a&gt;</code></pre></td>

            </tbody>
          </table>

          <h3>Methods</h3>
          <h4>.modal(options)</h4>
          <p>Activates your content as a modal. Accepts an optional options <code>object</code>.</p>
<pre class="prettyprint linenums">
$('#myModal').modal({
  keyboard: false

</pre>
          <h4>.modal('toggle')</h4>
          <p>Manually toggles a modal.</p>
          <pre class="prettyprint linenums">$('#myModal').modal('toggle')</pre>
          <h4>.modal('show')</h4>

          <h2>Usage</h2>

          <h3>Via data attributes</h3>
          <p>To easily add scrollspy behavior to your topbar navigation, just add <code>data-spy="scroll"</code> to the element you want to spy on (most typically this would be the body) and <code>data-target=".navbar"</code> to select which nav to use. You'll want to use scrollspy with a <code>.nav</code> component.</p>
          <pre class="prettyprint linenums">&lt;body data-spy="scroll" data-target=".navbar"&gt;...&lt;/body&gt;</pre>

          <h3>Via JavaScript</h3>
          <p>Call the scrollspy via JavaScript:</p>
          <pre class="prettyprint linenums">$('#navbar').scrollspy()</pre>

          <div class="alert alert-info">
            <strong>Heads up!</strong>
            Navbar links must have resolvable id targets. For example, a <code>&lt;a href="#home"&gt;home&lt;/a&gt;</code> must correspond to something in the dom like <code>&lt;div id="home"&gt;&lt;/div&gt;</code>.
          </div>

          <h3>Methods</h3>
          <h4>.scrollspy('refresh')</h4>
          <p>When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:</p>
<pre class="prettyprint linenums">
$('[data-spy="scroll"]').each(function () {
  var $spy = $(this).scrollspy('refresh')
});
</pre>

          <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-offset=""</code>.</p>
          <table class="table table-bordered table-striped">
            <thead>
             <tr>

          <h2>Usage</h2>
          <p>Enable tabbable tabs via JavaScript (each tab needs to be activated individually):</p>
<pre class="prettyprint linenums">
$('#myTab a').click(function (e) {
  e.preventDefault();
  $(this).tab('show');
})</pre>
          <p>You can activate individual tabs in several ways:</p>
<pre class="prettyprint linenums">
$('#myTab a[href="#profile"]').tab('show'); // Select tab by name
$('#myTab a:first').tab('show'); // Select first tab
$('#myTab a:last').tab('show'); // Select last tab
$('#myTab li:eq(2) a').tab('show'); // Select third tab (0-indexed)
</pre>

          <h3>Markup</h3>
          <p>You can activate a tab or pill navigation without writing any JavaScript by simply specifying <code>data-toggle="tab"</code> or <code>data-toggle="pill"</code> on an element. Adding the <code>nav</code> and <code>nav-tabs</code> classes to the tab <code>ul</code> will apply the Bootstrap tab styling.</p>
<pre class="prettyprint linenums">
