WCAG 2.1 AA Accessibility Checklist for Modern React & Next.js Developers

Why Digital Accessibility is a Legal Mandate in India

Digital accessibility ensures that all citizens—including those with visual, auditory, motor, or cognitive impairments—can perceive, understand, navigate, and interact with web technologies.

In India, accessibility is not merely an optional frontend best practice; it is a **statutory obligation** codified under: * The **Rights of Persons with Disabilities (RPwD) Act, 2016** (Mandating accessibility across all physical and electronic public infrastructure). * The **Guidelines for Indian Government Websites (GIGW 3.0)** (Mandating W3C WCAG 2.1 Level AA conformance).

Portals that fail basic accessibility checks are disqualified from STQC quality certification and cannot be deployed on sovereign government domains.

Essential React / Next.js Implementation Checklist

1. Semantic HTML over `<div>` Soup Screen readers rely on native HTML element landmarks (`<header>`, `<nav>`, `<main>`, `<article>`, `<footer>`) to provide jump navigation to blind citizens. ```tsx // Non-compliant <div onClick={handleClick} className="btn">Submit Form</div>

// Compliant <button type="button" onClick={handleClick} className="btn"> Submit Form </button> ```

2. Form Controls & Floating Labels Every form input must be programmatically associated with a visible text label: ```tsx <label htmlFor="panNumber" className="text-sm font-bold text-slate-700"> Enter 10-Digit PAN Number </label> <input id="panNumber" name="panNumber" type="text" aria-describedby="panHelp" className="border p-2 rounded" /> <p id="panHelp" className="text-xs text-slate-500"> Format: ABCDE1234F </p> ```

3. Screen Reader Skip Links Place a "Skip to Main Content" component as the very first interactive node inside your root layout: ```tsx <a href="#main-content" className="sr-only focus:not-sr-only focus:absolute focus:top-4 focus:left-4 focus:z-50 focus:px-4 focus:py-2 focus:bg-blue-600 focus:text-white focus:rounded-xl focus:shadow-xl" > Skip to Main Content </a> ```
