Blazor Badge

The Blazor Bootstrap Badge component shows the small count and labels.


Badges scale to match the size of the immediate parent element by using relative font sizing and em units. As of now, badges no longer have focus or hover styles for links.

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 VisuallyHiddenText parameter.

Pill badges#

Use the IndicatorType parameter to make badges more rounded with a larger border-radius.
Primary Secondary Success Danger Warning Info Light Dark
<Badge Color="BadgeColor.Primary" IndicatorType="BadgeIndicatorType.RoundedPill">Primary</Badge>
<Badge Color="BadgeColor.Secondary" IndicatorType="BadgeIndicatorType.RoundedPill">Secondary</Badge>
<Badge Color="BadgeColor.Success" IndicatorType="BadgeIndicatorType.RoundedPill">Success</Badge>
<Badge Color="BadgeColor.Danger" IndicatorType="BadgeIndicatorType.RoundedPill">Danger</Badge>
<Badge Color="BadgeColor.Warning" IndicatorType="BadgeIndicatorType.RoundedPill">Warning</Badge>
<Badge Color="BadgeColor.Info" IndicatorType="BadgeIndicatorType.RoundedPill">Info</Badge>
<Badge Color="BadgeColor.Light" IndicatorType="BadgeIndicatorType.RoundedPill">Light</Badge>
<Badge Color="BadgeColor.Dark" IndicatorType="BadgeIndicatorType.RoundedPill">Dark</Badge>


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

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.


Use Position and Placement parameters to position it in the corner of a link or button.

Generic indicator#

You can also replace the badge with a generic indicator without the count.
<Button Type="ButtonType.Button" Color="ButtonColor.Primary" Position="Position.Relative">
    <Badge Color="BadgeColor.Danger"
           VisuallyHiddenText="unread messages"></Badge>
