Badges scale to match the size of the immediate parent element by using relative font sizing and em
units.

Use utilities to modify a .badge
and position it in the corner of a link or button.
<button type="button" class="btn btn-success position-relative">
Inbox
<span class="position-absolute top-0 start-100 translate-middle badge rounded-pill bg-danger">
99+
<span class="visually-hidden">unread messages</span>
</span>
</button>
You can also replace the .badge
class with a few more utilities without a count
for a more generic indicator.
<button type="button" class="btn btn-warning position-relative">
