Accessibility is about making your web applications usable by as many people as possible, including those with disabilities. Here are some best practices to ensure your apps are inclusive.
Semantic HTML elements (like <header>, <nav>, <main>, <footer>, <button>, etc.) provide meaning and structure, making it easier for assistive technologies to interpret your content.
Always provide text alternatives for non-text content, such as images (alt attributes), icons, and media.
Text should have enough contrast with its background to be readable by users with low vision. Use tools like the WebAIM Contrast Checker to verify.
Ensure all interactive elements can be accessed and used with a keyboard. Avoid keyboard traps and provide visible focus indicators.
ARIA (Accessible Rich Internet Applications) attributes help convey additional information to assistive technologies. Use them to enhance, not replace, semantic HTML.
Test your app with screen readers (like NVDA, JAWS, or VoiceOver) to ensure content is announced correctly and navigation is logical.
Auto-playing audio or video can be disruptive. Allow users to control playback.
Designing for accessibility benefits everyone, not just users with disabilities. By following these best practices, you can create web applications that are more usable, inclusive, and successful.
