Example

Badges scale to match the size of the immediate parent element by using relative font sizing and em units. Badges come in three variants: solid (default), subtle, and outline.

New New New

HTML

<span class="badge theme-primary">New</span>
<span class="badge badge-subtle theme-primary">New</span>
<span class="badge badge-outline theme-primary">New</span>

Headings

Badges adapt to the font-size of the parent element.

Example heading New

HTML

<h1>Example heading <span class="badge">New</span></h1>
<h2>Example heading <span class="badge">New</span></h2>
<h3>Example heading <span class="badge">New</span></h3>
<h4>Example heading <span class="badge">New</span></h4>
<h5>Example heading <span class="badge">New</span></h5>
<h6>Example heading <span class="badge">New</span></h6>

Buttons

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

HTML

<button type="button" class="btn btn-primary">
  Notifications <span class="badge theme-danger">4</span>
</button>

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.

HTML

<button type="button" class="btn btn-primary position-relative">
  Inbox
  <span class="position-absolute top-0 start-100 translate-middle badge rounded-pill border border-bg theme-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.

HTML

<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-bg rounded-circle">
    <span class="visually-hidden">New alerts</span>
  </span>
</button>

Variants

Use the contextual .theme-{color} classes to apply a semantic theme color to badges.

Accessibility Tip: Using color to convey meaning

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

CSS

Variables

Badges use local CSS variables on .badge for real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

SCSS

--badge-padding-x: #{$badge-padding-x};
--badge-padding-y: #{$badge-padding-y};
--badge-font-size: #{$badge-font-size};
--badge-font-weight: #{$badge-font-weight};
--badge-color: #{$badge-color};
--badge-bg: var(--bg-2);
--badge-border-width: #{$border-width};
--badge-border-color: transparent;
--badge-border-radius: #{$badge-border-radius};

Sass variables

SCSS

$badge-font-size:                   clamp(12px, .75em, .75em);
$badge-font-weight:                 $font-weight-semibold;
$badge-color:                       inherit;
$badge-padding-y:                   .25em;
$badge-padding-x:                   .625em;
$badge-border-radius:               var(--border-radius-lg);
