Badges
Documentation and examples for badges, our small count and labeling component.
Example
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.
Headings
Buttons
Badges can be used as part of links or buttons to provide a counter.
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.
Positioned
Use utilities to modify a .badge and position it in the corner of a link or button.
You can also replace the .badge class with a few more utilities without a count for a more generic indicator.
Background colors
Set a background-color with contrasting foreground color with our .text-bg-{color} helpers. Previously it was required to manually pair your choice of .text-{color} and .bg-{color} utilities for styling, which you still may use if you prefer.
Pill badges
Use the .rounded-pill utility class to make badges more rounded with a larger border-radius.
CSS
Variables
As part of Bootstrap’s evolving CSS variables approach, badges now use local CSS variables on .badge for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
