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
.submit-btn { width: 140px; overflow: hidden; white-space: nowrap; }
.submit-btn .icon { position: absolute; right: 8px; } Why it matters
Under wider letter and word spacing, 'Submit Return' grows past the button's fixed 140px width and wraps directly behind the icon, becoming unreadable.
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
Let buttons grow with their label under spacing overrides instead of clipping or wrapping text behind a fixed icon.
.submit-btn { width: auto; min-width: 140px; padding: 10px 40px 10px 16px; white-space: normal; } Outcome
A filer with wider letter spacing reads 'Submit Return' clearly instead of a label mangled behind an icon.
Who is affected
Low-vision filers using custom text spacing can't read the submit button's label, risking a missed or unintended submission.
