Screen reader and keyboard accessibility requires semantic HTML elements, proper ARIA labels, and focus management. Use headings, lists, and form labels semantically; add ARIA attributes where native HTML lacks meaning; implement visible focus indicators and logical tab order to enable full keyboard operation without a mouse.

WCAG (Web Content Accessibility Guidelines) are internationally recognized standards ensuring web content works for people with disabilities. Compliance reduces legal risk, expands your user base, and improves usability for everyone—including users on slow networks or mobile devices.

Color contrast accessibility means ensuring text and interactive elements meet minimum luminosity ratios against their backgrounds. Test contrast ratios using automated tools, aim for WCAG AA standards (4.5:1 for body text), and adjust foreground or background colors until thresholds pass for all text sizes.

Yes, but retrofitting is slower and costlier than building accessibility in from the start. Begin by auditing your current UI for semantic HTML gaps, keyboard navigation barriers, and ARIA misuse; then prioritize fixes by impact—start with critical user flows and high-traffic pages.

Semantic HTML (headings, nav, main, form elements) is the foundation—use it first for native accessibility. ARIA (Accessible Rich Internet Applications) supplements semantic HTML when you need custom widgets or dynamic content; it cannot replace proper HTML structure and requires JavaScript to manage state.

Automated tools catch common issues like color contrast and missing alt text, but full accessibility validation requires manual testing with actual screen readers and keyboard-only navigation. Combine automated scanning with user testing involving people with disabilities for comprehensive coverage.
