Accessibility guidance is often either legalistic or hand-wavy; WebAIM is neither, giving you the principles and the concrete practices in plain language. Start here to understand contrast, semantic structure, keyboard focus, and why they matter, then use their contrast checker in daily work. It is the most trustworthy free on-ramp to the topic.
What you will learn
- The POUR principles
- Contrast, semantics, and keyboard access basics
- How disabilities intersect with design decisions
How to study it
- Documentation is not for linear reading. Learn the mental model of the tool elsewhere first.
- Then use the docs as lookup while you build something real, answering specific questions as they arise.
- Keep it open in a tab during practice. It earns its value in application, not memorization.
