Badges
Documentation and examples for badges, our small count and labeling component.
Examples
Badges scale to match the size of the immediate parent element by using relative font sizing and em
units. Badges don’t have focus or hover styles for links.

<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 text-bg-secondary">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 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="/innovation-cup/docs/0.2/assets/img/boosted-sprite.svg#buy"/>
</svg>
<span class="visually-hidden">Shopping basket</span>
<span class="position-absolute top-0 start-100 translate-middle badge rounded-pill text-bg-warning">
99+
<span class="visually-hidden">shopping basket items</span>
</span>
</a>
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.
<span class="badge text-bg-primary">Primary</span>
<span class="badge text-bg-secondary">Secondary</span>
<span class="badge text-bg-success">Success</span>
<span class="badge text-bg-danger">Danger</span>
<span class="badge text-bg-warning">Warning</span>
<span class="badge text-bg-info">Info</span>
<span class="badge text-bg-light">Light</span>
<span class="badge text-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
Use the .rounded-pill
utility class to make badges more rounded with a larger border-radius
.
<span class="badge rounded-pill text-bg-primary">Primary</span>
<span class="badge rounded-pill text-bg-secondary">Secondary</span>
<span class="badge rounded-pill text-bg-success">Success</span>
<span class="badge rounded-pill text-bg-danger">Danger</span>
<span class="badge rounded-pill text-bg-warning">Warning</span>
<span class="badge rounded-pill text-bg-info">Info</span>
<span class="badge rounded-pill text-bg-light">Light</span>
<span class="badge rounded-pill text-bg-dark">Dark</span>
CSS
Variables
As part of Boosted Innovation Cup’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.
--#{$prefix}badge-padding: #{subtract(var(--#{$prefix}badge-padding-y), 1px) var(--#{$prefix}badge-padding-x) add(var(--#{$prefix}badge-padding-y), 1px)}; // Boosted mod
--#{$prefix}badge-padding-x: #{$badge-padding-x};
--#{$prefix}badge-padding-y: #{$badge-padding-y};
@include rfs($badge-font-size, --#{$prefix}badge-font-size);
--#{$prefix}badge-font-weight: #{$badge-font-weight};
--#{$prefix}badge-color: #{$badge-color};
--#{$prefix}badge-border-radius: #{$badge-border-radius};
Sass variables
$badge-font-size: .75em;
$badge-font-weight: $font-weight-bold;
$badge-color: $white;
$badge-padding-y: .35em;
$badge-padding-x: .65em;
$badge-border-radius: $border-radius;
