title: Badges

Badges are indicators for new or unread activity and include support for the active states of our [navigation components](/components/navs/), links, buttons, and more.
{% example html %}
<a href="#">Inbox <span class="badge">42</span></a>
{% endexample %}
### Self collapsing
When there are no new or unread items, badges will simply collapse (via CSS's `:empty` selector) provided no content exists within.
### Active nav
Built-in styles are included for placing badges in active states in pill navigations.
{% example html %}
<ul class="nav nav-pills" role="tablist">
<li class="nav-item active" role="presentation">
<a class="nav-link" href="#">Home <span class="badge">42</span></a>
</li>
<li class="nav-item" role="presentation">
<a class="nav-link" href="#">Profile</a>
</li>
<li class="nav-item" role="presentation">
<a class="nav-link" href="#">Messages <span class="badge">3</span></a>
</li>
</ul>
{% endexample %}
### Buttons
Like active nav links, badges in Bootstrap buttons automatically restyle to better blend into the background.
{% example html %}
<button class="btn btn-primary btn-lg" type="button">
Large button <span class="badge">4</span>
</button>
<button class="btn btn-primary" type="button">
Button <span class="badge">4</span>
</button>
<button class="btn btn-primary btn-sm" type="button">
Small button <span class="badge">4</span>
</button>
<button class="btn btn-primary btn-xs" type="button">
Extra small <span class="badge">4</span>
</button>
{% endexample %}
