Badges

Small and adaptive tag for adding context to just about any content.

Overview

Badges scale to match the size of the immediate parent element by using relative font sizing and em units.

<div>
  <h2>Example heading <b-badge>New</b-badge></h2>
  <h3>Example heading <b-badge>New</b-badge></h3>
  <h4>Example heading <b-badge>New</b-badge></h4>
  <h5>Example heading <b-badge>New</b-badge></h5>
  <h6>Example heading <b-badge>New</b-badge></h6>
</div>

<!-- b-badges.vue -->

Badges can be used as part of links or buttons to provide a counter (or similar flag).

<div class="text-center">
  <b-button variant="primary">
    Notifications <b-badge variant="light">4</b-badge>
  </b-button>
</div>

<!-- b-badge-button.vue -->

Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.

Unless the context is clear (as with the "Notifications" example, where it is understood that the "4" is the number of notifications), consider including additional context with a visually hidden piece of additional text.

<div class="text-center">
  <b-button variant="primary">
    Profile
    <b-badge variant="light">9 <span class="sr-only">unread messages</span></b-badge>
  </b-button>
</div>

<!-- b-badge-button-aria.vue -->

Contextual variations

Add any of the following variants via the variant prop to change the appearance of a <b-badge>: default, primary, success, warning, info, and danger. If no variant is specified default will be used.

<div>
  <b-badge variant="primary">Primary</b-badge>
  <b-badge variant="secondary">Secondary</b-badge>
  <b-badge variant="success">Success</b-badge>
  <b-badge variant="danger">Danger</b-badge>
  <b-badge variant="warning">Warning</b-badge>
  <b-badge variant="info">Info</b-badge>
  <b-badge variant="light">Light</b-badge>
  <b-badge variant="dark">Dark</b-badge>
</div>

<!-- b-badge-variants.vue -->

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.

Pill badges

Use the pill prop to make badges more rounded (with a larger border-radius and additional horizontal padding). Useful if you miss the badges from Bootstrap v3.

<div>
  <b-badge pill variant="primary">Primary</b-badge>
  <b-badge pill variant="secondary">Secondary</b-badge>
  <b-badge pill variant="success">Success</b-badge>
  <b-badge pill variant="danger">Danger</b-badge>
  <b-badge pill variant="warning">Warning</b-badge>
  <b-badge pill variant="info">Info</b-badge>
  <b-badge pill variant="light">Light</b-badge>
  <b-badge pill variant="dark">Dark</b-badge>
</div>

<!-- b-badge-pill.vue -->

Actionable badges

Quickly provide actionable badges with hover and focus states by specifying either the href prop (links) or to prop (router-links):

<div>
  <b-badge href="#" variant="primary">Primary</b-badge>
  <b-badge href="#" variant="secondary">Secondary</b-badge>
  <b-badge href="#" variant="success">Success</b-badge>
  <b-badge href="#" variant="danger">Danger</b-badge>
  <b-badge href="#" variant="warning">Warning</b-badge>
  <b-badge href="#" variant="info">Info</b-badge>
  <b-badge href="#" variant="light">Light</b-badge>
  <b-badge href="#" variant="dark">Dark</b-badge>
</div>

<!-- b-badge-action.vue -->

<b-badge> Properties

Properties

Property (Click to sort Ascending)	Type	Default	Description
`href`	`String`		Denotes the target URL of the link for standard a links
`rel`	`String`	`null`	Sets the 'rel' attribute on the rendered link
`target`	`String`	`'_self'`	Sets the 'target' attribute on the rendered link
`active`	`Boolean`	`false`	When set to 'true', places the component in the active state with active styling
`disabled`	`Boolean`	`false`	When set to 'true', disables the component's functionality and places it in a disabled state
`to`	`String` or `Object`		router-link prop: Denotes the target route of the link. When clicked, the value of the to prop will be passed to router.push() internally, so the value can be either a string or a Location descriptor object
`append`	`Boolean`	`false`	router-link prop: Setting append prop always appends the relative path to the current path
`replace`	`Boolean`	`false`	router-link prop: Setting the replace prop will call 'router.replace()' instead of 'router.push()' when clicked, so the navigation will not leave a history record
`event`	`String` or `Array`	`'click'`	router-link prop: Specify the event that triggers the link. In most cases you should leave this as the default
`active-class`	`String`		router-link prop: Configure the active CSS class applied when the link is active. Typically you will want to set this to class name 'active'
`exact`	`Boolean`	`false`	router-link prop: The default active class matching behavior is inclusive match. Setting this prop forces the mode to exactly match the route
`exact-active-class`	`String`		router-link prop: Configure the active CSS class applied when the link is active with exact match. Typically you will want to set this to class name 'active'
`router-tag`	`String`	`'a'`	router-link prop: Specify which tag to render, and it will still listen to click events for navigation. 'router-tag' translates to the tag prop on the final rendered router-link. Typically you should use the default value
`no-prefetch`	`Boolean`	`false`	nuxt-link prop: To improve the responsiveness of your Nuxt.js applications, when the link will be displayed within the viewport, Nuxt.js will automatically prefetch the code splitted page. Setting 'no-prefetch' will disabled this feature for the specific link
`tag`	`String`	`'span'`	Specify the HTML tag to render instead of the default tag
`variant` Settings	`String`	`'secondary'`	Applies one of the Bootstrap theme color variants to the component
`pill`	`Boolean`	`false`	When set to 'true', renders the badge in pill style

<b-badge> supports generating <router-link> or <nuxt-link> component (if using Nuxt.js). For more details on the router link (or nuxt link) specific props, see the Router support reference section.
