Accessibility Best Practices

Building accessible interfaces increases reach and quality. Focus on semantics, keyboard support, and clear ARIA usage.

Essentials

• Use semantic HTML (button, nav, main, header).
• Ensure keyboard navigation and focus order.
• Provide meaningful alt text and labels.
• Maintain color contrast and avoid color-only cues.
• Use ARIA only when native semantics aren't available.

Testing

• Manual keyboard testing and screen reader checks (NVDA, VoiceOver).
• Automated tools: axe, Lighthouse, WAVE — combine with manual tests.

<button aria-pressed="false">Toggle</button>

Accessibility is iterative — include it in design and QA cycles.
