Accessibility gets treated as a nice extra. For a growing number of your buyers it is a legal requirement, and an item that fails it is disqualified before price is considered.
The four that catch almost everything
- Contrast. Light grey on white fails, and it is the single most common failure in items sold here
- Keyboard. Every action reachable without a mouse, with a visible focus ring you did not remove
- Labels. Every input with a real label, not a placeholder that vanishes when typing starts
- Alt text. Meaningful images described, decorative ones marked as decorative
Do not remove the focus outline
Somebody always does, because it looks untidy. For a keyboard user it is the cursor. If you dislike the default, replace it with something clearer rather than deleting it.
Colour cannot be the only signal
A red row meaning failed and a green row meaning passed are the same row to a colour blind user. Add an icon, a word, a shape. This costs nothing and is missed constantly.
Test it in ten minutes
Unplug your mouse and try to complete the main task. Then run any free contrast checker over your palette. Those two passes find most of it, and neither needs specialist knowledge.
It is a selling point
Public sector buyers, universities and large companies frequently must meet a standard. Saying plainly what yours meets puts you on a shortlist that most competing items are not on.
