Button Label That Vanishes Under Increased Text Spacing

1.4.12 — Text Spacing

Scenario

Setting

A government tax-filing portal

What’s wrong

Buttons whose labels vanish or wrap behind icons under spacing overrides.

Example

A QA pass on a government tax-filing portal turns this up: buttons whose labels vanish or wrap behind icons under spacing overrides.

Why it matters

People with dyslexia or low vision who apply extra text spacing to read. On a government tax-filing portal specifically, they can't perceive the control's boundary or state.

How to test

Apply the text-spacing override to button labels: if the label text vanishes or wraps behind an icon, it fails.

How to fix

With user text-spacing overrides applied (line height 1.5, paragraph 2x, letter 0.12em, word 0.16em), all content and controls must remain visible and usable.

Outcome

Fixed, a visitor to a government tax-filing portal can see the control's boundary and current state.

Who is affected

People with dyslexia or low vision who apply extra text spacing to read.
