Documentation and examples for badges, our small count and labeling component.


Badges scale to match the size of the immediate parent element by using relative font sizing and em units. As of v5, badges no longer have focus or hover styles for links.

Badges can be used as part of links or buttons to provide a counter.

<button type="button" class="btn btn-primary">
  Notifications <span class="badge bg-secondary">4</span>

Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.

Unless the context is clear (as with the “Notifications” example, where it is understood that the “4” is the number of notifications), consider including additional context with a visually hidden piece of additional text.


Use utilities to modify a .badge and position it in the corner of a link with an icon.

<a href="#" class="position-relative">
  <svg width="2rem" height="2rem" fill="currentColor" aria-hidden="true" focusable="false" class="overflow-visible">
    <use xlink:href="/docs/5.1/assets/img/boosted-sprite.svg#buy"/>
  <span class="visually-hidden">Shopping basket</span>
  <span class="position-absolute top-0 start-100 translate-middle badge rounded-pill bg-info text-white">
    <span class="visually-hidden">shopping basket items</span>

Background colors

Use our background utility classes to quickly change the appearance of a badge. Please note that when using Boosted’s default .bg-light, you’ll likely need a text color utility like .text-dark for proper styling. This is because background utilities do not set anything but background-color.

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .visually-hidden class.

Pill badges

Use the .rounded-pill utility class to make badges more rounded with a larger border-radius.
