♿ Accessibility Checker

What is Accessibility Testing?

Web accessibility ensures that websites and applications are usable by everyone, including people with disabilities. This tool checks your website against the Web Content Accessibility Guidelines (WCAG) 2.2 — the international standard for web accessibility.

WCAG 2.2 Principles

WCAG is organized around four core principles:

• Perceivable — Information must be presentable in ways users can perceive (text alternatives, captions, adaptable content)
• Operable — Interface components must be operable (keyboard accessible, enough time, navigable)
• Understandable — Information and operation must be understandable (readable, predictable, input assistance)
• Robust — Content must be robust enough for assistive technologies (valid markup, compatible)

What This Tool Checks

• ✅ Images — Alt text presence for screen readers
• ✅ Headings — Proper hierarchy (h1 → h2 → h3)
• ✅ Forms — Label associations, autocomplete attributes
• ✅ Links — Meaningful link text, not "click here"
• ✅ Page Structure — Title, language, landmarks, skip links
• ✅ Keyboard — Tabindex issues, focusable elements
• ✅ ARIA — Proper usage, required attributes
• ✅ Tables — Headers, captions for data tables

Limitations

Automated testing can identify many accessibility issues, but some checks require manual review:

• Color contrast (requires visual rendering)
• Meaningful alt text quality
• Keyboard focus visibility
• Screen reader compatibility
• Cognitive accessibility

We recommend using this tool alongside manual testing with screen readers (NVDA, VoiceOver) and keyboard-only navigation.
