  • Home/End: Move to first/last tab
  • Enter/Space: Activate the focused tab (if not automatic)

Why This Matters

ARIA (Accessible Rich Internet Applications) attributes bridge the gap between custom widgets and assistive technologies. But misused ARIA does more harm than good — the first rule of ARIA is 'No ARIA is better than bad ARIA.' This tool helps you generate correct, complete ARIA markup following WAI-ARIA 1.2 patterns.

How to Use This Tool

  1. 1

    Select a pattern

    Choose from common UI patterns like tabs, dialogs, menus, alerts, live regions, and more.

  2. 2

    Configure attributes

    Fill in the form with your element's ID, CSS classes, and ARIA attribute values. Required attributes are marked.

  3. 3

    Review the code

    The generated HTML or JSX updates in real-time with proper roles, states, and properties.

  4. 4

    Copy and paste

    Switch between HTML and JSX output, then copy the code into your project.

Frequently Asked Questions

Use ARIA when semantic HTML alone cannot convey the role, state, or property of a custom widget. If a native HTML element exists (e.g., <button>), use it instead of adding role="button" to a <div>.
