<h1>Example heading <CBadge color="secondary">New</CBadge></h1>
<h2>Example heading <CBadge color="secondary">New</CBadge></h2>
<h3>Example heading <CBadge color="secondary">New</CBadge></h3>
<h4>Example heading <CBadge color="secondary">New</CBadge></h4>
<h5>Example heading <CBadge color="secondary">New</CBadge></h5>
<h6>Example heading <CBadge color="secondary">New</CBadge></h6>

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

<CButton color="primary">
  Notifications <CBadge color="secondary">4</CBadge>
</CButton>

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.

<CButton color="primary">
  Profile <CBadge color="secondary">9</CBadge>
  <span class="visually-hidden">unread messages</span>
</CButton>

Positioned #

Use position prop to modify a component and position it in the corner of a link or button.

<CButton color="primary" class="position-relative">
  Profile
  <CBadge color="danger" position="top-start" shape="rounded-pill">
    99+ <span class="visually-hidden">unread messages</span>
  </CBadge>
</CButton>
<CButton color="primary" class="position-relative">
  Profile
  <CBadge color="danger" position="top-end" shape="rounded-pill">
    99+ <span class="visually-hidden">unread messages</span>
  </CBadge>
</CButton>
<CButton color="primary" class="position-relative">
  Profile
  <CBadge color="danger" position="bottom-start" shape="rounded-pill">
    99+ <span class="visually-hidden">unread messages</span>
  </CBadge>
</CButton>
<CButton color="primary" class="position-relative">
  Profile
  <CBadge color="danger" position="bottom-end" shape="rounded-pill">
    99+ <span class="visually-hidden">unread messages</span>
  </CBadge>
</CButton>

You can also create more generic indicators without a counter using a few more utilities.

<CButton color="primary" class="position-relative">
  Profile
  <CBadge class="border border-light p-2" color="danger" position="top-end" shape="rounded-circle">
    <span class="visually-hidden">New alerts</span>
  </CBadge>
</CButton>

Customizing #

CSS variables #

Vue 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.

--cui-badge-padding-x: #{$badge-padding-x};
--cui-badge-padding-y: #{$badge-padding-y};
--cui-badge-font-size: #{$badge-font-size};
--cui-badge-font-weight: #{$badge-font-weight};
--cui-badge-color: #{$badge-color};
--cui-badge-border-radius: #{$badge-border-radius};

How to use CSS variables #

const vars = { 
  '--my-css-var': 10,
  '--my-another-css-var': "red" 
}
return <CBadge :style="vars">...</CBadge>

SASS variables #

$badge-font-size:                   .75em;
$badge-font-weight:                 $font-weight-bold;
$badge-color:                       $high-emphasis-inverse;
$badge-padding-y:                   .35em;
$badge-padding-x:                   .65em;
$badge-border-radius:               $border-radius;

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