Level AA · WCAG 2.1
1.4.12 Text Spacing
Users can override line height, paragraph spacing, letter spacing and word spacing without content being cut off or overlapping.
Partly automated Some failures are detectable, others need judgement.
How it fails in practice
A card with a fixed height where increased line spacing pushes the last line behind the card’s footer.
How to fix it
Use min-height instead of height anywhere text lives, and stop setting line-height in pixels.

How far an automated check gets
A tool finds some failures here and cannot see the rest. A clean automated result means the checks that exist found nothing — not that the criterion is met. This is the gap that makes a green scan look like an accessible site, and it is where our agents and a human reviewer do the remaining work.
