WCAG 2.2 Accessibility for React Developers - Practical Guide

I'm Safdar Ali, a frontend engineer in Bengaluru. Last quarter I audited a client dashboard that looked polished - clean Tailwind, smooth transitions, Lighthouse performance in the 90s - and failed basic keyboard navigation in under two minutes. Tab order jumped randomly, modals trapped nothing, and icon-only buttons had no labels.

WCAG 2.2 is not a legal checkbox for enterprise contracts alone. It is how you ship React UI that works for everyone: screen reader users, keyboard-only users, people on slow 4G with zoom enabled, and your future self debugging at 11pm. This guide covers the WCAG 2.2 React patterns I run before every merge.

Why WCAG 2.2 matters for React in 2026

WCAG 2.2 added criteria that directly affect React apps: focus not obscured, dragging movements, target size minimums, and consistent help. React's component model makes accessibility both easier and easier to break - you can encapsulate good patterns in a shared Dialog component, but you can also copy-paste a div-with-onClick button across forty files.

The legal landscape in India is catching up. Government portals and fintech products increasingly require accessibility audits before launch. Even when nobody asks, inclusive UI reduces support tickets - unclear error messages and broken focus management generate more "the form is broken" emails than actual backend failures.

React does not ship accessible components by default. A <button> is focusable; a <div> is not, unless you wire it. Your job is to make the accessible path the default path in your design system.

Focus traps - modals that actually work

A focus trap keeps keyboard focus inside a modal until the user dismisses it. Without one, Tab sends focus to elements behind the overlay - confusing for sighted keyboard users and disorienting for screen reader users who hear content from two layers at once.
