Zoom & reflow per WCAG
People with low vision enlarge the page. WCAG 1.4.4 requires text to scale to 200% without loss of function or content; 1.4.10 requires reflow without horizontal scrolling at 320 px width.
Common mistakes
<meta name="viewport" content="…, user-scalable=no"> or maximum-scale=1 (locks the zoom), font sizes in px with fixed container heights, horizontal scrolling on strong zoom.
How to do it right
Remove user-scalable and maximum-scale from the viewport meta. Use relative units (rem) and flexible layouts. Test at 400% / 320 px.
