WCAG 1.3.3 Level A Perceivable

1.3.3 Sensory Characteristics

Instructions do not rely solely on shape, size, position, or sound ("click the round button on the right").

What 1.3.3 Sensory Characteristics means

Users who cannot perceive colour, shape or location still understand instructions.

How to test

Look for instructions that depend only on visual/sensory cues.

How to meet it

Add text labels or names alongside any positional/shape/colour cue (e.g. "Select Submit (the round button on the right)").
