Example

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

{% highlight html %}

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

{% capture example %} Notifications 4 {% endcapture %} {% include example.html content=example %}

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.

{% capture example %} Profile 9 unread messages {% endcapture %} {% include example.html content=example %}

Contextual variations

Add any of the below mentioned modifier classes to change the appearance of a badge.

{% capture example %} {% for color in site.data.theme-colors %} {{ color.name | capitalize }}{% endfor %} {% endcapture %} {% include example.html content=example %}

{% include callout-warning-color-assistive-technologies.md %}

Pill badges

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

{% capture example %} {% for color in site.data.theme-colors %} {{ color.name | capitalize }}{% endfor %} {% endcapture %} {% include example.html content=example %}

Links

Using the contextual .badge-* classes on an <a> element quickly provide actionable badges with hover and focus states.

{% capture example %} {% for color in site.data.theme-colors %} {{ color.name | capitalize }}{% endfor %} {% endcapture %} {% include example.html content=example %}
