Support CoreUI Development
CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.
You can support our Open Source software development in the following ways:
- Buy the CoreUI PRO, and get access to PRO components, and dedicated support.
- Became a sponsor, and get your logo on BACKERS.md/README.md files or each site of this documentation
- Give us a star ⭐️ on Github.

React badges can be used as part of links or buttons to provide a counter.
1<CButton color="primary">2 Notifications <CBadge color="secondary">4</CBadge>3</CButton>
Remark that depending on how you use them, react 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.
1<CButton color="primary">2 Profile <CBadge color="secondary">9</CBadge>3 <span className="visually-hidden">unread messages</span>4</CButton>
Positioned#
Use position prop to modify a component and position it in the corner of a link or button.
1<CButton color="primary" className="position-relative">2 Profile3 <CBadge color="danger" position="top-start" shape="rounded-pill">4 99+ <span className="visually-hidden">unread messages</span>5 </CBadge>6</CButton>7<CButton color="primary" className="position-relative">8 Profile9 <CBadge color="danger" position="top-end" shape="rounded-pill">10 99+ <span className="visually-hidden">unread messages</span>11 </CBadge>12</CButton>13<br/>14<CButton color="primary" className="position-relative">15 Profile16 <CBadge color="danger" position="bottom-start" shape="rounded-pill">17 99+ <span className="visually-hidden">unread messages</span>18 </CBadge>19</CButton>20<CButton color="primary" className="position-relative">21 Profile22 <CBadge color="danger" position="bottom-end" shape="rounded-pill">23 99+ <span className="visually-hidden">unread messages</span>24 </CBadge>25</CButton>
You can also create more generic indicators without a counter using a few more utilities.
1<CButton color="primary" className="position-relative">2 Profile3 <CBadge4 className="border border-light p-2"5 color="danger"6 position="top-end"7 shape="rounded-circle"8 >9 <span className="visually-hidden">New alerts</span>10 </CBadge>11</CButton>

1<CBadge color="primary">primary</CBadge>2<CBadge color="success">success</CBadge>3<CBadge color="danger">danger</CBadge>4<CBadge color="warning">warning</CBadge>5<CBadge color="info">info</CBadge>6<CBadge color="light">light</CBadge>7<CBadge color="dark">dark</CBadge>

1<CBadge color="primary" shape="rounded-pill">primary</CBadge>2<CBadge color="success" shape="rounded-pill">success</CBadge>3<CBadge color="danger" shape="rounded-pill">danger</CBadge>4<CBadge color="warning" shape="rounded-pill">warning</CBadge>5<CBadge color="info" shape="rounded-pill">info</CBadge>6<CBadge color="light" shape="rounded-pill">light</CBadge>7<CBadge color="dark" shape="rounded-pill">dark</CBadge>
Customizing#
CSS variables#
React badges use local CSS variables on .badges for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
1--cui-badge-padding-x: #{$badge-padding-x};2--cui-badge-padding-y: #{$badge-padding-y};3--cui-badge-font-size: #{$badge-font-size};4--cui-badge-font-weight: #{$badge-font-weight};5--cui-badge-color: #{$badge-color};6--cui-badge-border-radius: #{$badge-border-radius};
How to use CSS variables#
1const vars = {2 '--my-css-var': 10,3 '--my-another-css-var': 'red',4}5return <CBadge style={vars}>...</CBadge>
SASS variables#
1$badge-font-size: .75em;2$badge-font-weight: $font-weight-bold;3$badge-color: $high-emphasis-inverse;4$badge-padding-y: .35em;5$badge-padding-x: .65em;6$badge-border-radius: $border-radius;78$badge-font-size-sm: .65em;9$badge-padding-y-sm: .3em;10$badge-padding-x-sm: .5em;
