A badge notification is a small circular visual indicator that informs users about unread messages, notifications, or updates.^[1] It's a concise and unobtrusive way to alert users to new activities or information within an application without requiring them to open it immediately. Once users see the updates, badge notifications generally disappear.

There are two main types of badge notifications:

• Count badges display a numerical value indicating the quantity of new items or notifications, such as unread messages or pending tasks.
• Dot badges use a simple dot to signify the presence of new content without specifying the exact count.

The best way to style a badge notification is to make it noticeable yet harmonious with the overall design. Consider using contrasting colors to ensure visibility while maintaining aesthetic coherence.
