+ <h4>Tooltips & 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>

+ <h4>Ensure correct <code>role</code> and provide a label</h4>
+ <p>In order for assistive technologies – such as screen readers – to convey that a series of buttons is grouped, an appropriate <code>role</code> attribute needs to be provided. For button groups, this would be <code>role="group"</code>, while toolbars should have a <code>role="toolbar"</code>.</p>
+ <p>One exception are groups which only contain a single control (for instance the <a href="#btn-groups-justified">justified button groups</a> with <code><button></code> elements) or a dropdown.</p>
+ <p>In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct <code>role</code> attribute. In the examples provided here, we use <code>aria-label</code>, but alternatives such as <code>aria-labelledby</code> can also be used.</p>

+ <h2 id="btn-groups-justified">Justified button groups</h2>
+ <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" id="callout-btn-group-justified-dbl-border">
+ <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" id="callout-btn-group-ie8-border">
+ <h4>IE8 and borders</h4>
+ <p>Internet Explorer 8 doesn't render borders on buttons in a justified button group, whether it's on <code><a></code> or <code><button></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>
