      <p>When using tooltips or popovers on elements within a <code>.btn-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>

    <div class="bs-callout bs-callout-danger">
      <h4>Cross-browser compatibility</h4>
      <p>Avoid using <code>&lt;select&gt;</code> elements here as they cannot be fully styled in WebKit browsers.</p>

      <h4>Tooltips &amp; popovers in input groups require special setting</h4>
      <p>When using tooltips or popovers on elements within an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>

    <p>Note the <code>.nav-tabs</code> class requires the <code>.nav</code> base class.</p>
    <div class="bs-example">
      <ul class="nav nav-tabs">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">Profile</a></li>
        <li><a href="#">Messages</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="nav nav-tabs">
  <li class="active"><a href="#">Home</a></li>
  <li><a href="#">Profile</a></li>
  <li><a href="#">Messages</a></li>
</ul>
{% endhighlight %}

    <h2 id="nav-pills">Pills</h2>
    <p>Take that same HTML, but use <code>.nav-pills</code> instead:</p>
    <div class="bs-example">
      <ul class="nav nav-pills">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">Profile</a></li>
        <li><a href="#">Messages</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="nav nav-pills">
  <li class="active"><a href="#">Home</a></li>
  <li><a href="#">Profile</a></li>
  <li><a href="#">Messages</a></li>
</ul>
{% endhighlight %}
    <p>Pills are also vertically stackable. Just add <code>.nav-stacked</code>.</p>
    <div class="bs-example">
      <ul class="nav nav-pills nav-stacked" style="max-width: 300px;">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">Profile</a></li>
        <li><a href="#">Messages</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="nav nav-pills nav-stacked">
  ...
</ul>
{% endhighlight %}


    <h2 id="nav-justified">Justified</h2>
    <p>Easily make tabs or pills equal widths of their parent with <code>.nav-justified</code>.</p>
    <div class="bs-example">
      <ul class="nav nav-tabs nav-justified">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">Profile</a></li>
        <li><a href="#">Messages</a></li>
      </ul>
      <br>
      <ul class="nav nav-pills nav-justified">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">Profile</a></li>
        <li><a href="#">Messages</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="nav nav-tabs nav-justified">
  ...
</ul>
<ul class="nav nav-pills nav-justified">
  ...
</ul>
{% endhighlight %}


    <h2 id="nav-disabled-links">Disabled links</h2>
    <p>For any nav component (tabs, pills, or list), add <code>.disabled</code> for <strong>gray links and no hover effects</strong>.</p>

    <div class="bs-callout bs-callout-warning">
      <h4>Link functionality not impacted</h4>
      <p>This class will only change the <code>&lt;a&gt;</code>'s appearance, not its functionality. Use custom JavaScript to disable links here.</p>
    </div>

    <div class="bs-example">
      <ul class="nav nav-pills">
        <li><a href="#">Clickable link</a></li>
        <li><a href="#">Clickable link</a></li>
        <li class="disabled"><a href="#">Disabled link</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="nav nav-pills">
  ...
  <li class="disabled"><a href="#">Disabled link</a></li>
  ...
</ul>
{% endhighlight %}


    <h2 id="nav-alignment">Alignment options</h2>
    <p>To align nav links, use the <code>.pull-left</code> or <code>.pull-right</code> utility classes. Both classes will add a CSS float in the specified direction.</p>


    <h2 id="nav-dropdowns">Using dropdowns</h2>
    <p>Add dropdown menus with a little extra HTML and the <a href="../javascript/#dropdowns">dropdowns JavaScript plugin</a>.</p>

    <h3>Tabs with dropdowns</h3>
    <div class="bs-example">
      <nav class="navbar" role="navigation">

  <!-- Navbar

    </div>

    <h2 id="navbar-default">Default navbar</h2>
    <p>Navbars are responsive meta components that serve as navigation headers for your application or site. They begin collapsed (and are toggleable) in mobile views and become horizontal as the available viewport width increases.</p>

    <div class="bs-callout bs-callout-info">
      <h4>Customize the collapsing point</h4>
      <p>Depending on the content in your navbar, you might need to change the point at which your navbar switches between collapsed and horizontal mode. Customize the <code>@grid-float-breakpoint</code> variable or add your own media query.</p>
    </div>

    <div class="bs-example">
      <nav class="navbar" role="navigation">

  <h4>Make navbars accessible</h4>
  <p>Be sure to add a <code>role="navigation"</code> to every navbar to help with accessibility.</p>

    <h2 id="navbar-text">Text</h2>
    <p>Wrap strings of text in an element with <code>.navbar-text</code>, usually on a <code>&lt;p&gt;</code> tag for proper leading and color.</p>

    <h2 id="navbar-component-alignment">Component alignment</h2>
    <p>Align nav links, forms, buttons, or text, using the <code>.navbar-left</code> or <code>.navbar-right</code> utility classes. Both classes will add a CSS float in the specified direction. For example, to align nav links, put them in a separate <code>&lt;ul&gt;</code> with the respective utility class applied.</p>
    <p>These classes are mixin-ed versions of <code>.pull-left</code> and <code>.pull-right</code>, but they're scoped to media queries for easier handling of navbar components across device sizes.</p>


    <h2 id="navbar-fixed-top">Fixed to top</h2>
    <p>Add <code>.navbar-fixed-top</code>.</p>

  <!-- Pagination
  ================================================== -->
  <div class="bs-docs-section">
    <div class="page-header">

    </div>
    <p class="lead">Provide pagination links for your site or app with the multi-page pagination component, or the simpler <a href="#pagination-pager">pager alternative</a>.</p>

    <h2 id="pagination-default">Default pagination</h2>
    <p>Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.</p>
    <div class="bs-example">
      <ul class="pagination">
        <li><a href="#">&laquo;</a></li>
        <li><a href="#">1</a></li>
        <li><a href="#">2</a></li>
        <li><a href="#">3</a></li>
        <li><a href="#">4</a></li>
        <li><a href="#">5</a></li>
        <li><a href="#">&raquo;</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="pagination">
  <li><a href="#">&laquo;</a></li>
  <li><a href="#">1</a></li>
  <li><a href="#">2</a></li>
  <li><a href="#">3</a></li>
  <li><a href="#">4</a></li>
  <li><a href="#">5</a></li>
  <li><a href="#">&raquo;</a></li>
</ul>
{% endhighlight %}

    <h3>Disabled and active states</h3>
    <p>Links are customizable for different circumstances. Use <code>.disabled</code> for unclickable links and <code>.active</code> to indicate the current page.</p>
    <div class="bs-example">
      <ul class="pagination">
        <li class="disabled"><a href="#">&laquo;</a></li>
        <li class="active"><a href="#">1 <span class="sr-only">(current)</span></a></li>
        <li><a href="#">2</a></li>
        <li><a href="#">3</a></li>
        <li><a href="#">4</a></li>
        <li><a href="#">5</a></li>
        <li><a href="#">&raquo;</a></li>
     </ul>
    </div>
{% highlight html %}
<ul class="pagination">
  <li class="disabled"><a href="#">&laquo;</a></li>
  <li class="active"><a href="#">1 <span class="sr-only">(current)</span></a></li>
  ...
</ul>
{% endhighlight %}
    <p>You can optionally swap out active or disabled anchors for <code>&lt;span&gt;</code> to remove click functionality while retaining intended styles.</p>
{% highlight html %}
<ul class="pagination">
  <li class="disabled"><span>&laquo;</span></li>
  <li class="active"><span>1 <span class="sr-only">(current)</span></span></li>
  ...
</ul>
{% endhighlight %}


    <h3>Sizing</h3>
    <p>Fancy larger or smaller pagination? Add <code>.pagination-lg</code> or <code>.pagination-sm</code> for additional sizes.</p>
    <div class="bs-example">
      <div>
        <ul class="pagination pagination-lg">
          <li><a href="#">&laquo;</a></li>

          <li><a href="#">2</a></li>
          <li><a href="#">3</a></li>
          <li><a href="#">4</a></li>
          <li><a href="#">5</a></li>

<ul class="pagination pagination-sm">...</ul>
{% endhighlight %}


    <h2 id="pagination-pager">Pager</h2>
    <p>Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.</p>

    <h3>Default example</h3>
    <p>By default, the pager centers links.</p>
    <div class="bs-example">
      <ul class="pager">
        <li><a href="#">Previous</a></li>
        <li><a href="#">Next</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="pager">
  <li><a href="#">Previous</a></li>
  <li><a href="#">Next</a></li>
</ul>
{% endhighlight %}

    <h3>Aligned links</h3>
    <p>Alternatively, you can align each link to the sides:</p>
    <div class="bs-example">
      <ul class="pager">
        <li class="previous"><a href="#">&larr; Older</a></li>
        <li class="next"><a href="#">Newer &rarr;</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="pager">
  <li class="previous"><a href="#">&larr; Older</a></li>
  <li class="next"><a href="#">Newer &rarr;</a></li>
</ul>
{% endhighlight %}


    <h3>Optional disabled state</h3>
    <p>Pager links also use the general <code>.disabled</code> utility class from the pagination.</p>
    <div class="bs-example">
      <ul class="pager">
        <li class="previous disabled"><a href="#">&larr; Older</a></li>
        <li class="next"><a href="#">Newer &rarr;</a></li>
      </ul>
    </div>
{% highlight html %}
<ul class="pager">

    <h4>Self collapsing</h4>

    <h3 id="list-group-basic">Basic example</h3>
    <p>The most basic list group is simply an unordered list with list items, and the proper classes. Build upon it with the options that follow, or your own CSS as needed.</p>
    <div class="bs-example">

    <h3 id="list-group-badges">Badges</h3>
    <p>Add the badges component to any list group item and it will automatically be positioned on the right.</p>
    <div class="bs-example">
      <ul class="list-group">
        <li class="list-group-item">

    <h3 id="list-group-linked">Linked items</h3>
    <p>Linkify list group items by using anchor tags instead of list items (that also means a parent <code>&lt;div&gt;</code> instead of an <code>&lt;ul&gt;</code>). No need for individual parents around each element.</p>
    <div class="bs-example">

  <a href="#" class="list-group-item">Vestibulum at eros</a>
</div>
{% endhighlight %}

    <h3 id="list-group-custom-content">Custom content</h3>
    <p>Add nearly any HTML within, even for linked list groups like the one below.</p>
