Why is accessibility important?
It expands your audience, improves SEO, and ensures compliance with laws like ADA or WCAG.

Detailed Tips or Best Practices
1. Add Alt Text for Images
Always provide descriptive `alt` attributes to help screen readers interpret visuals.
2. Use ARIA Landmarks When Needed
ARIA roles like `role=button` or `aria-label` enhance screen reader context.
3. Test with Screen Readers
Try NVDA, VoiceOver, or TalkBack to simulate real user experiences.
4. Avoid Color-Only Cues
Use text labels or icons in addition to color to ensure readability for color-blind users.
5. Validate with Tools
Use tools like axe DevTools, Lighthouse, or WAVE to audit accessibility issues.
Conclusion
Accessibility should not be an afterthought—it’s a foundation of ethical design. Follow WCAG and a11y best practices to create inclusive web experiences for all users.
