Diagnoses

Here is how rule engines diagnose the meta bans zoom issue for HTML element 22 of the Institute for Agriculture and Trade Policy donate page.

1. Zooming and scaling must not be disabled; user-scalable=no on <meta> tag disables zooming on mobile devices

   Rule engine: Axe (Deque)

   Rule: meta-viewport

2. The viewport must let users zoom to at least 200%

   Rule engine: Pour (David Yarham and Geoffrey Crofte)

   Rule: meta-viewport

3. [failed] The `meta` element with a `name='viewport'` attribute abolishes the user agent ability to zoom with user-scalable=no or maximum-scale < 2.

   Rule engine: QualWeb (University of Lisbon)

   Rule: QW-ACT-R14

4. This viewport meta tag restricts the user's ability to zoom (user-scalable=no, maximum-scale=1).

   Rule engine: SureA11y (Jorge Rumoroso)

   Rule: meta-viewport-zoom-enabled
