What is Web Accessibility?
Example
<!-- Accessibility checklist basics:
1. Images have meaningful alt text
2. Headings follow logical order (h1 > h2 > h3)
3. Form inputs have associated labels
4. Color contrast ratio >= 4.5:1 for normal text
5. Interactive elements are keyboard-navigable
6. ARIA roles used where HTML semantics are insufficient -->
<!-- Check with: axe DevTools, WAVE, or Lighthouse --> Pro Tip
Run your page through Lighthouse Accessibility audit — it catches the most common issues.
