WCAG 1.4.4 Resize Text
Level AA
Users must be able to scale text up to 200% in their browser without loss of content or functionality and without horizontal scrolling.
Common failures
- Layout breaks with overlapping text at 150-200% zoom.
- Critical buttons are clipped when text wraps.
- Site uses `font-size: 12px` everywhere with no relative units.
How to fix
- Use relative units (`rem`, `em`, `%`) for font sizing.
- Test the site at 200% zoom across breakpoints.
- Allow text containers to grow vertically rather than truncating.
