About the Button with Notification Badge

A notification badge is a small overlay on a button that indicates a change in status or a number of new items requiring the user's attention. Its bright color and strategic placement make it stand out. For accessibility, it's important that the button's text or aria-label reflects the notification's content, so the information isn't purely visual.

Features

High Visibility: The badge uses a high-contrast color and is positioned on the corner of the button to be easily noticed.
Flexible Content: The badge can display a number or be used as a simple dot for a more minimal look (by removing the number).
Accessible Implementation: The button text includes the notification count so screen reader users hear the full context, such as "Notifications, 3 new items." The badge itself is hidden from screen readers with aria-hidden="true" to avoid redundant announcements.
Pure CSS Positioning: The badge is perfectly positioned using CSS relative and absolute positioning.

Code Breakdown

The structure consists of a button element with its position set to relative. Inside the button are the button text and a span element for the badge. The badge's position is set to absolute, which allows it to be positioned relative to the corners of its parent button. By adding aria-hidden="true" to the badge and including its information in the button's primary text, we ensure the component is usable by everyone.
