When talking about web accessibility, the story starts and ends with semantic markup. Let's learn what that means and how to leverage it in our apps.

Playful Programming

A guide to web accessibility through semantic HTML markup. Covers replacing div-soup with meaningful HTML elements, using landmark elements (header, main, nav, section, etc.) for page structure, and how screen readers like VoiceOver, NVDA, and JAWS interact with these elements. Also explains ARIA attributes (aria-expanded, aria-controls, aria-selected) and the role attribute for custom UI patterns. Includes a practical walkthrough of building an accessible, keyboard-navigable tab component in React with proper ARIA roles and W3C-compliant keyboard bindings.
