Examples

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

Headings

Example heading New

html

<h1>Example heading <span class="badge text-bg-secondary">New</span></h1>
<h2>Example heading <span class="badge text-bg-secondary">New</span></h2>
<h3>Example heading <span class="badge text-bg-secondary">New</span></h3>
<h4>Example heading <span class="badge text-bg-secondary">New</span></h4>
<h5>Example heading <span class="badge text-bg-secondary">New</span></h5>
<h6>Example heading <span class="badge text-bg-secondary">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 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.

html

<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.

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-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.

Primary Secondary Success Danger Warning Info Light Dark

html

<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

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-success">Success</span>
<span class="badge rounded-pill text-bg-danger">Danger</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>

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.

scss/_badge.scss

--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

scss/_variables.scss

$badge-font-size:                   .75em;
$badge-font-weight:                 $font-weight-bold;
$badge-color:                       $white;
$badge-padding-y:                   .35em;
$badge-padding-x:                   .65em;
$badge-border-radius:               var(--#{$prefix}border-radius);

$badge-font-size-sm:                .65em;
$badge-padding-y-sm:                .3em;
$badge-padding-x-sm:                .5em;

CoreUI vs Bootstrap

While this Badge component is fully compatible with Bootstrap and follows its core principles, CoreUI delivers a more complete solution for modern app development.

What sets CoreUI apart from Bootstrap?

✅ Fully compatible with Bootstrap – Built directly on Bootstrap, all classes and behaviors work as expected.
🧠 Framework-native versions – CoreUI provides dedicated libraries for React.js, Vue.js, and Angular, unlike Bootstrap which relies on third-party plugins for JavaScript frameworks.
👨‍💻 Maintained by a full-time team – CoreUI is developed as a professional product, not a volunteer-driven project.
📦 More built-in components – Includes additional ready-to-use components like range sliders, multi-selects, steppers, etc.
🛠️ Sass Modules support today – CoreUI already supports Sass Modules, which are planned for Bootstrap 6.
🌍 Better LTR/RTL support – Uses modern CSS logical properties for seamless bidirectional layout support.
🔒 LTS (Long-Term Support) – Bootstrap now offers LTS only via paid third parties like HeroDevs, while CoreUI continues to offer long-term support natively and for free.

Whether you’re building internal tools, dashboards, or SaaS platforms — CoreUI combines the familiarity of Bootstrap with a more powerful, scalable, and production-ready ecosystem.
