accessibility

WCAG accessibility standards require semantic HTML markup, keyboard navigation, sufficient color contrast, ARIA labels, and visible focus indicators. Audit your components against these criteria to identify gaps in conformance, then prioritize fixes for semantic structure, keyboard support, screen reader labels, color contrast ratios, and focus management to ensure usability for all users.

Semantic HTML uses proper elements like <button>, <nav>, and <heading> to convey meaning and structure, enabling screen readers and assistive technologies to interpret content correctly. Semantic markup is foundational to accessibility because it provides programmatic structure that assistive tech relies on to help users with disabilities navigate and understand your interface.

Keyboard navigation requires making all interactive elements reachable via Tab key, implementing logical focus order, and providing visible focus indicators. Ensure keyboard users can activate buttons, navigate menus, and operate form controls without a mouse by managing focus state and accepting keyboard input across all interactive UI elements.

ARIA attributes like aria-label, aria-describedby, aria-expanded, and role attributes provide context to screen readers when semantic HTML alone is insufficient. Apply meaningful ARIA labels to unlabeled buttons, indicate dynamic state changes, and assign appropriate roles so assistive technology users understand component purpose and current state.

No; color contrast and visual cues must work together but not depend on color alone. Maintain sufficient contrast ratios between text and background, use icons or text labels alongside color coding, and ensure users with color blindness can perceive all meaningful distinctions without relying on hue differences.

Systematically review components for semantic HTML correctness, keyboard operability, ARIA labeling completeness, color contrast compliance, and focus management. Create a prioritized checklist of issues across these dimensions, then address high-impact gaps first to bring your library into WCAG conformance across all components.
