Selected Tab or Item Text Failing the Contrast Minimum

1.4.3 — Contrast (Minimum)

Scenario

Setting

A job board's application form

What’s wrong

Selected/current item text (e.g., active tab white-on-light-blue) failing.

Example

Open a job board's application form and this is what you'll see: selected/current item text (e.g., active tab white-on-light-blue) failing.

Why it matters

Low-vision and older readers, plus anyone viewing a dim or sunlit screen. On a job board's application form, that means they can't perceive the control's boundary or state.

How to test

Measure the currently selected item (active tab, chosen filter) against its own highlighted background — selection styling often drops contrast below default state.

How to fix

The text must meet at least 4.5:1 contrast (3:1 for large text) against its actual background in every state (default, hover, focus, selected).

Outcome

With the fix in place on a job board's application form, they tell the information apart without relying on color.

Who is affected

Low-vision and older readers, plus anyone viewing a dim or sunlit screen.
