Build websites everyone can use. Start from semantic HTML, make every interaction work with the keyboard, add ARIA only where HTML falls short, and meet the WCAG Level AA bar that teams and laws are measured against — all with plain web-platform examples that work in any framework.
Accessibility builds on the HTML you write every day.
Semantic HTML
Accessibility starts with the right element — use real buttons, links, headings, and landmarks so the browser gives you keyboard support and screen-reader meaning for free.
Keyboard & Focus
Many users never touch a mouse — make every interaction reachable with Tab, keep a visible focus ring, and manage focus in modals so keyboard users never get lost.
ARIA — Roles, States & Live Regions
ARIA fills the gaps HTML can’t — learn roles, properties, and states, when an aria-label helps, how to announce dynamic updates with live regions, and the first rule of ARIA: don’t use it if HTML already does the job.
Meeting WCAG (Level AA)
WCAG is the standard everyone is measured against — hit Level AA with sufficient color contrast, labelled accessible forms, support for reduced motion, and correct page language and titles.
