Accessibility is about inclusivity and legal compliance. WCAG 2.2 outlines standards for accessible design. Use sufficient contrast for readability. Ensure all images have alt text. Enable keyboard navigation. Provide captions for videos. Use clear, structured HTML markup. Avoid content that flashes or auto-plays. Make error messages specific and helpful. Ensure forms have proper labels. Use ARIA roles where appropriate. Test with screen readers. Avoid relying solely on color to convey information. Maintain responsive design for various devices. Regularly audit your site for compliance. Accessibility improves UX for everyone—not just users with disabilities.
