1.3.3 Sensory Characteristics
Instructions cannot rely only on shape, color, size, position or sound, as in "click the round button on the right".
Who it helps
Blind and low-vision people, and people who use a different layout such as a phone view.
Failures we see most
- "Press the green button to continue"
- "See the sidebar on the left" on a page that stacks into one column on phones
How it gets tested
No automated tool can judge 1.3.3 reliably, so a specialist tests it by hand, with a keyboard and a screen reader where that applies.
How we fix it
A specialist fixes this in your site's code or content, and we re-test the page before you sign off.
