    <h4>Tooltips &amp; popovers in button groups require special setting</h4>
    <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>

  <h3 id="btn-groups-single">Basic example</h3>
  <p>Wrap a series of buttons with <code>.btn</code> in <code>.btn-group</code>.</p>

  <h3 id="btn-groups-justified">Justified button groups</h3>
  <p>Make a group of buttons stretch at equal sizes to span the entire width of its parent. Also works with button dropdowns within the button group.</p>

  <div class="bs-callout bs-callout-warning">
    <h4>Handling borders</h4>
    <p>Due to the specific HTML and CSS used to justify buttons (namely <code>display: table-cell</code>), the borders between them are doubled. In regular button groups, <code>margin-left: -1px</code> is used to stack the borders instead of removing them. However, <code>margin</code> doesn't work with <code>display: table-cell</code>. As a result, depending on your customizations to Bootstrap, you may wish to remove or re-color the borders.</p>
  </div>
  <div class="bs-callout bs-callout-warning">
    <h4>IE8 and borders</h4>
    <p>Internet Explorer 8 doesn't render borders in on buttons in a justified button group, whether it's on <code>&lt;a&gt;</code> or <code>&lt;button&gt;</code> elements. To get around that, wrap each button in another <code>.btn-group</code>.</p>
    <p>See <a href="https://github.com/twbs/bootstrap/issues/12476">#12476</a> for more information.</p>
  </div>

  <h4>With <code>&lt;a&gt;</code> elements</h4>
  <p>Just wrap a series of <code>.btn</code>s in <code>.btn-group.btn-group-justified</code>.</p>
  <div class="bs-example">
    <div class="btn-group btn-group-justified">
      <a class="btn btn-default" role="button">Left</a>
      <a class="btn btn-default" role="button">Middle</a>
      <a class="btn btn-default" role="button">Right</a>

    <br>
    <div class="btn-group btn-group-justified">
      <a class="btn btn-default" role="button">Left</a>
      <a class="btn btn-default" role="button">Middle</a>
      <div class="btn-group">
        <a class="btn btn-default dropdown-toggle" data-toggle="dropdown">
          Dropdown <span class="caret"></span>
        </a>
        <ul class="dropdown-menu" role="menu">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li class="divider"></li>
          <li><a href="#">Separated link</a></li>

  <h4>With <code>&lt;button&gt;</code> elements</h4>
  <p>To use justified button groups with <code>&lt;button&gt;</code> elements, <strong class="text-danger">you must wrap each button in a button group</strong>. Most browsers don't properly apply our CSS for justification to <code>&lt;button&gt;</code> elements, but since we support button dropdowns, we can workaround that.</p>
  <div class="bs-example">
    <div class="btn-group btn-group-justified">
      <div class="btn-group">
        <button type="button" class="btn btn-default">Left</button>
      </div>
      <div class="btn-group">
        <button type="button" class="btn btn-default">Middle</button>
      </div>
      <div class="btn-group">
        <button type="button" class="btn btn-default">Right</button>
