Success Criterion 1.4.11
Conformance level AA

Hover or Pressed State That Drops Below Contrast Minimum

1.4.11 — Non-text Contrast

Scenario

Setting

A ride-hailing app's trip booking screen

What’s wrong

Control state variants (hover, checked, pressed) dropping below 3:1 even where the default state passes.

Example

border: 1px solid #dcdcdc; /* icon outline, ~1.2:1 against white */

Why it matters

Low-vision and color-blind people who need to perceive controls and meaningful graphics.

How to test

Measure every interactive state (hover, checked, pressed) separately with a contrast checker: a state passing in default but dropping below 3:1 when hovered/checked/pressed fails.

How to fix

The visual element (border, icon, indicator, state marker) must have at least 3:1 contrast against adjacent colors in every state. border: 1px solid #767676; /* ~4.5:1 */ Icons, borders, and other non-text UI elements need at least 3:1 contrast to stay visible.

Outcome

On a ride-hailing app's trip booking screen, this barrier is gone for low-vision and color-blind people who need to perceive controls and meaningful graphics — they no longer have to work around this.
