Badge component scales to suit the size of the parent element by using relative font sizing and em units.

Basic usage

vue

<template>
  <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>
</template>

<script setup>
import { CBadge } from '@coreui/vue'
</script>

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

vue

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

<script setup>
import { CButton, CBadge } from '@coreui/vue'
</script>

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.

vue

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

<script setup>
import { CButton, CBadge } from '@coreui/vue'
</script>

Positioned

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

vue

<template>
  <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 ms-1">
    Profile
    <CBadge color="danger" position="top-end" shape="rounded-pill">
      99+ <span class="visually-hidden">unread messages</span>
    </CBadge>
  </CButton>
  <br />
  <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 ms-1">
    Profile
    <CBadge color="danger" position="bottom-end" shape="rounded-pill">
      99+ <span class="visually-hidden">unread messages</span>
    </CBadge>
  </CButton>
</template>

<script setup>
import { CButton, CBadge } from '@coreui/vue'
</script>

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

vue

<template>
  <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>
</template>

<script setup>
import { CButton, CBadge } from '@coreui/vue'
</script>

Contextual variations

Add any of the below-mentioned color props to modify the presentation of a badge.

vue

<template>
  <CBadge color="primary">primary</CBadge>
  <CBadge color="success">success</CBadge>
  <CBadge color="danger">danger</CBadge>
  <CBadge color="warning">warning</CBadge>
  <CBadge color="info">info</CBadge>
  <CBadge textBgColor="light">light</CBadge>
  <CBadge color="dark">dark</CBadge>
</template>

<script setup>
import { CBadge } from '@coreui/vue'
</script>

You can also apply contextual variations with the textBgColor property, which automatically sets the text color to ensure compliance with the WCAG 4.5:1 contrast ratio standard for enhanced accessibility.

vue

<template>
  <CBadge textBgColor="primary">primary</CBadge>
  <CBadge textBgColor="success">success</CBadge>
  <CBadge textBgColor="danger">danger</CBadge>
  <CBadge textBgColor="warning">warning</CBadge>
  <CBadge textBgColor="info">info</CBadge>
  <CBadge textBgColor="light">light</CBadge>
  <CBadge textBgColor="dark">dark</CBadge>
</template>

<script setup>
import { CBadge } from '@coreui/vue'
</script>

Pill badges

Apply the shape="rounded-pill" prop to make badges rounded.

vue

<template>
  <CBadge color="primary" shape="rounded-pill">primary</CBadge>
  <CBadge color="success" shape="rounded-pill">success</CBadge>
  <CBadge color="danger" shape="rounded-pill">danger</CBadge>
  <CBadge color="warning" shape="rounded-pill">warning</CBadge>
  <CBadge color="info" shape="rounded-pill">info</CBadge>

</template>

<script setup>
import { CBadge } from '@coreui/vue'
</script>
