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

Bootstrap 4 documentation

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

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

<button type="button" class="btn btn-primary">
    Messages <span class="badge badge-danger">9</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.

<button type="button" class="btn btn-primary">
    Notifications <span class="badge badge-pill badge-white">5</span>
    <span class="sr-only">unread messages</span>
Contextual variations

Add any of the below mentioned modifier classes to change the appearance of a badge.

Primary Secondary Tertiary Success Danger Warning Info Light Dark
<span class="badge badge-primary text-uppercase">Primary</span>
<span class="badge badge-secondary text-uppercase">Secondary</span>
<span class="badge badge-tertiary text-uppercase">Tertiary</span>
<span class="badge badge-success text-uppercase">Success</span>
<span class="badge badge-danger text-uppercase">Danger</span>
<span class="badge badge-warning text-uppercase">Warning</span>
<span class="badge badge-info text-uppercase">Info</span>
<span class="badge badge-light text-uppercase">Light</span>
<span class="badge badge-dark text-uppercase">Dark</span>
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 .sr-only class.

Pill Badges

Use the .badge-pill modifier class to make badges more rounded (with a larger border-radius and additional horizontal padding). Useful if you miss the badges from v3.
