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> 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 CoreUI for 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.
<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> Conveying meaning to assistive technologies
Relying on color to convey meaning creates a visual cue that assistive technologies, like screen readers, cannot perceive. It’s essential that any information represented by color is either apparent from the content itself (e.g., the visible text) or supplemented by alternative methods, such as extra text using the .visually-hidden class.
Pill badges
Apply the .rounded-pill modifier class to make badges rounded.
<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> Customizing
CSS variables
Badges 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.
--cui-badge-padding-x: #{$badge-padding-x};
--cui-badge-padding-y: #{$badge-padding-y};
@include rfs($badge-font-size, --cui-badge-font-size);
--cui-badge-font-weight: #{$badge-font-weight};
--cui-badge-color: #{$badge-color};
--cui-badge-border-radius: #{$badge-border-radius}; SASS variables
