Instructions must not rely only on shape, size, colour, or position ("click the round button on the right").

Level APerceivable

What it means

Instructions must not rely only on shape, size, colour, or position ("click the round button on the right").

How to meet it

Reference elements by their visible label or name, not just sensory cues.

How AccessScan checks this

This criterion needs a rendered page or human judgement (for example colour contrast, focus visibility, or media review), so it’s part of manual testing and our upcoming deep scan rather than the free static scan.
