Bootstrap badges

Bootstrap badge is small count and labeling components.

Examples

Bootstrap badge scale to suit the size of the parent element by using relative font sizing and em units.

<h4>Example heading <span class="badge bg-secondary">New</span></h4>
<h5>Example heading <span class="badge bg-secondary">New</span></h5>
<h6>Example heading <span class="badge bg-secondary">New</span></h6>

Buttons

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>
</button>

Remark that depending on how you use them, badges may be complicated for users of screen readers and related assistive technologies.

Unless the context is clear, 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.

<button type="button" class="btn btn-primary 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-primary position-relative">
  Profile
  <span class="position-absolute top-0 start-100 translate-middle p-2 bg-danger border border-light rounded-circle">
    <span class="visually-hidden">New alerts</span>
  </span>
</button>

Contextual variations

Add any of the below-mentioned classes to modify the presentation of a badge. Please note that when using Bootstrap’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.

Primary Secondary Success Danger Warning Info Light Dark
<span class="badge bg-primary">Primary</span>
<span class="badge bg-secondary">Secondary</span>
<span class="badge bg-success">Success</span>
<span class="badge bg-danger">Danger</span>
<span class="badge bg-warning text-dark">Warning</span>
<span class="badge bg-info text-dark">Info</span>
<span class="badge bg-light text-dark">Light</span>
<span class="badge bg-dark">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 .visually-hidden class.

Pill badges

Apply the .rounded-pill modifier class to make badges rounded.

Primary Secondary Success Danger Warning Info Light Dark
<span class="badge rounded-pill bg-primary">Primary</span>
<span class="badge rounded-pill bg-secondary">Secondary</span>
<span class="badge rounded-pill bg-success">Success</span>
<span class="badge rounded-pill bg-danger">Danger</span>
<span class="badge rounded-pill bg-warning text-dark">Warning</span>
<span class="badge rounded-pill bg-info text-dark">Info</span>
<span class="badge rounded-pill bg-light text-dark">Light</span>
<span class="badge rounded-pill bg-dark">Dark</span>
