Badges
Easily highlight new or unread items by adding a <span class="badge"> to links, Bootstrap navs, and more.
<a href="#">Inbox <span class="badge">42</span></a>
<button class="btn btn-primary" type="button">
Messages <span class="badge">4</span>
</button>Self collapsing
When there are no new or unread items, badges will simply collapse (via CSS's :empty selector) provided no content exists within.
Cross-browser compatibility
Badges won't self collapse in Internet Explorer 8 because it lacks support for the :empty selector.
Adapts to active nav states
Built-in styles are included for placing badges in active states in pill navigations.
<ul class="nav nav-pills" role="tablist">
<li role="presentation" class="active"><a href="#">Home <span class="badge">42</span></a></li>
<li role="presentation"><a href="#">Profile</a></li>
<li role="presentation"><a href="#">Messages <span class="badge">3</span></a></li>
</ul>
