Make structure understandable
Use one descriptive page heading, logical subheadings, meaningful link text and properly marked lists. People using screen readers or keyboard navigation should be able to understand and move through the page without visual guesswork.
Keep text and media perceivable
Use sufficient contrast, readable type, useful image alternatives and captions or transcripts where relevant. Do not place registration dates or other essential information only inside a graphic.
Test tasks with different inputs
Navigate menus, forms and dialogs using a keyboard, check focus visibility and test at high zoom. Automated checks help, but real task testing and feedback reveal barriers tools cannot understand.
Questions
Frequently asked questions
Is mobile-friendly the same as accessible?
No. Responsive layout helps, but accessibility also covers structure, input, perception and assistive technology.
Do all images need descriptions?
Meaningful images need useful alternatives; purely decorative images should not add unnecessary screen-reader noise.
Can automated tools prove compliance?
No. They identify some issues, but manual testing and informed review remain necessary.
