<p class="lead">Group a series of buttons together on a single line with the button group. Add on optional JavaScript radio and checkbox style behavior with <a href="{{ site.baseurl }}/javascript/#buttons">our buttons plugin</a>.</p>
<div class="bs-callout bs-callout-warning" id="callout-btn-group-tooltips">
<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>
</div>
<div class="bs-callout bs-callout-warning" id="callout-btn-group-accessibility">
<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>
</div>
<h4>With <code><a></code> elements</h4>
<p>Just wrap a series of <code>.btn</code>s in <code>.btn-group.btn-group-justified</code>.</p>

<h4>Links acting as buttons</h4>
<p>If the <code><a></code> elements are used to act as buttons – triggering in-page functionality, rather than navigating to another document or section within the current page – they should also be given an appropriate <code>role="button"</code>.</p>
</div>
<h4>With <code><button></code> elements</h4>
<p>To use justified button groups with <code><button></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><button></code> elements, but since we support button dropdowns, we can work around that.</p>
