> Do you think we need a WCAG Low Vision failure to specifically address resizing viewports? My thought would be we would have one that covers up to 200% as part of current WCAG with the user agent note that most desktop browsers ignore the viewport maximum and thus a user agent that ignored it would allow it to pass as well similar to how SC 1.4.4 works with desktop browser zoom in general. And then we would create a more broad low vision failure that addresses viewport scale beyond 200% or perhaps less than 100%. For many people with low vision 200% won't be sufficient and for other people for example with RP may want to reduce the size of the text below 100%.

Adopting the text from 1.4.2 in UAAG 2.0 and maybe 1.4.1 and 1.4.3 too might help. http://www.w3.org/TR/UAAG20/#sc_142 Best Regards, Laura On 7/15/15, Jonathan Avila <jon.avila@ssbbartgroup.com> wrote: >> "yes, please use viewport meta to make content responsive.
