Description
Under WCAG 2.2 Success Criterion 1.4.10 (Reflow), the requirement is that content reflows without loss of information or functionality down to 320 CSS pixels wide (equivalent to 400% zoom on a 1280px desktop).
On mobile devices that already have a 320px wide viewport, when a user zooms to 400% the effective viewport can shrink to ~80px wide.
My question:
– Is there any requirement to support 200% or 400% zoom when you're on mobile, so 320px width would go to 80px?
