Frontend Accessibility

Screen reader accessibility requires semantic HTML tags that convey structure, ARIA attributes for dynamic content, keyboard navigation support, and proper focus management. Implement these by using heading hierarchies, form labels, alt text, and ensuring all interactive elements are keyboard-operable without mouse dependency.

Color contrast compliance ensures readability for users with low vision. Check text-to-background ratios against WCAG standards, avoid relying on color alone to convey meaning, and test your design with contrast checkers to meet minimum brightness ratios for normal and large text.

Accessible forms require explicit labels paired with inputs, semantic HTML input types, ARIA live regions or role attributes for dynamic error announcements, and keyboard navigation through all fields. Screen readers must announce required fields, validation errors, and available keyboard shortcuts.

Yes. Interactive components need focus traps, keyboard event handlers for arrow keys and Enter/Escape, ARIA roles describing widget type, and focus management that returns focus appropriately after closing. Test with keyboard-only and screen-reader workflows to verify full navigation.

Semantic HTML—buttons, nav, main, article, form—conveys structure and purpose directly to assistive technologies without extra ARIA. Screen readers announce element type and role automatically, reducing manual labeling and improving navigation efficiency for users with disabilities.

Check JSX/TSX components for missing alt attributes on images, unlabeled form inputs, keyboard traps, insufficient focus management, hard-coded colors without contrast checking, and ARIA attributes that conflict with semantic structure. Use automated testing and manual screen-reader validation to catch issues early.
