Web accessibility guides
Short, sourced, code-oriented guides for applying WCAG 2.2 and RGAA. Each guide gives the rules, an example, the test to run and the relevant RGAA criteria.
All guides
Start with the fundamentals guide, then go deeper by topic.
Fundamentals
The complete guide: POUR principles, keyboard, forms, ARIA, overlays, testing, i18n.
Keyboard navigation
Tab order, visible focus, skip link, keyboard traps and WCAG 2.4.11.
Accessible forms
Labels, errors, grouping, autocomplete and accessible authentication.
Cognitive accessibility
Plain language, clear steps, controlled animations, immediate feedback.
ARIA best practices
Native HTML first, then aria-label, aria-expanded, aria-live and role=alert.
Accessible media
Captions, transcripts, audio description and accessible controls.
Mobile accessibility
Touch targets, zoom, orientation, VoiceOver and TalkBack.
How to read these guides
Each recommendation is tied to a WCAG or RGAA criterion where relevant. Code samples are deliberately short: adapt them to your framework. Manual tests are listed because automated tools only catch part of the defects.
