Viewport Zoom

Checks that viewport doesn’t disable user zoom

Rule ID	mobile/viewport-zoom
Category	Mobile
Scope	Per-page
Severity	error
Weight	7/10

Solution

Never disable user zoom with maximum-scale=1, user-scalable=no, or user-scalable=0. Users with visual impairments need to zoom. This is an accessibility violation (WCAG 1.4.4). It also harms usability for all users. Remove these properties from your viewport meta tag.
