Overview
Accessible web experiences account for different ways people see, hear, move, understand, and interact with content. Semantic HTML, keyboard operation, text alternatives, sufficient contrast, clear labels, and predictable behavior help assistive technologies and also improve usability for many people without disabilities. Accessibility is a continuing product quality rather than a one-time visual checklist.
Structure and controls matter
Native headings, links, buttons, labels, and landmarks expose meaning and behavior to browsers and assistive technology. Styling generic containers to look interactive does not automatically provide keyboard behavior, names, roles, states, or focus handling.
Testing needs more than one method
Automated checks can catch some missing labels, invalid relationships, and contrast problems, but they cannot establish that every workflow makes sense. Keyboard testing, screen-reader checks, zoom and reflow checks, and review by people with relevant disabilities provide additional evidence.
