Accessibility Checklist

Every web application should meet WCAG 2.1 AA standards. This checklist covers the most impactful items.

Keyboard Navigation

All interactive elements must be reachable and operable via keyboard. Use visible focus indicators. Test by unplugging your mouse and navigating with Tab, Enter, and Escape.

Color Contrast

Text must have a contrast ratio of at least 4.5:1 against its background (3:1 for large text). Use tools like the Chrome DevTools contrast checker to verify.

Semantic HTML

Use the right elements: button for actions, a for navigation, h1-h6 for headings in order. Screen readers depend on proper semantics to convey structure.
