Building Accessible React Components That Everyone Can Use

Accessibility ensures apps are usable for everyone, including people with disabilities. Accessible React components improve usability, compliance, and overall UX

Semantic HTML

Use proper elements

• <button> instead of <div> for clicks
• <label> + <input> for forms

==Example:==

<label htmlFor="email">Email</label>
<input type="email" id="email" />
Keyboard Navigation
Support key events:


const handleKeyDown = (e) => {
  if (e.key === 'Enter') openModal();
};

ARIA Roles

• [x] Use when semantic HTML is insufficient:

• [x]aria-label

• [x] aria-expanded

aria-live

==Example:==

<button aria-label="Close modal">×</button>

Focus Management

Trap focus in modals

useEffect(() => {
  modalRef.current.focus();
}, []);

Color Contrast

Ensure sufficient contrast (4.5:1) and avoid relying on color alone to convey information

Testing

Use tools like Axe DevTools, Lighthouse, and screen readers (VoiceOver/NVDA)

Wrap-Up

Integrating accessibility from the start improves inclusivity and UX. Small tweaks make significant differences without compromising design or usability
