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.
