Accessibility shouldn't be an afterthought. Here are my go-to resources:

The A11y Project

  • Checklists for common patterns
  • Semantic HTML guidelines
  • Real-world examples

WebAIM

  • In-depth articles on accessibility
  • WCAG guidelines explained
  • Testing resources

axe DevTools

  • Browser extension for accessibility testing
  • Integrates with CI/CD
  • Great for catching issues early

The best accessibility tip: Test with a screen reader. NVDA (free) or VoiceOver (built-in) will reveal issues automated tools miss.
