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, consider including additional context with a visually hidden piece of additional text.

Pill badges

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