Building Accessible Interfaces

Best practices for creating web interfaces that everyone can use, from semantic HTML to ARIA patterns.

Building Accessible Interfaces

Accessibility is not a feature — it’s a fundamental requirement. This post covers the essential practices every developer should follow.

Semantic HTML

Use the right element for the job. <button> for buttons, <nav> for navigation, <main> for primary content.

Color Contrast

Ensure a minimum contrast ratio of 4.5:1 for body text and 3:1 for large text. Tools like Lighthouse and axe can audit your contrast automatically.

Keyboard Navigation

Every interactive element must be reachable and operable via keyboard. Test your site by tabbing through it without a mouse.
