Re: Jonathan's concern: Zoom in responsive drops content

2) Alastair — yes we do use some terms like essential and “undermine the purpose”  in WCAG… Just pushing to see if we can get to it better.



AC: Ok, damn, it’s hard though.



How about the last part is: “except for elements of the page where the spatial layout is required for its use.”



I don’t know how else to say that linearization would destroy the purpose of the content/functionality. The definition of essential was pretty good for that purpose; it is one of those ‘appropriate’ things that is not automatable.

3) Alastair — yes a big problem is that we ONLY have pinch-zoom (Screen zoom) on mobile.    we should define what the other should look like and send it in to accessibility@apple.com   and to other mobile browser mfgrs      Got an idea for a gesture for that?    (keyboard is usually   CTR+  or CMD+ )



AC: I think it needs to be a setting. You still need pinch-zoom for non-responsive layouts and that is the mobile equivalent of cmd+.



The issue is when a site sets the meta-viewport to device-width, then the ‘layout sizing’ (pinch-zoom, the magnification style) means you cannot reflow content.



I would like a setting such as: “Pinch-zoom reflows for mobile-optimized sites”. When ticked the pinch zoom works as it does now for non-responsive sites, but on a responsive site it allows you to increase the size of everything whilst re-flowing within the viewport.



On a medium size device (e.g. tablet) that could trigger media queries like on desktop, reflowing down to one column. Once you are on the smallest media-query defined (usually the one-column ‘mobile view’) it just keeps getting bigger and applies a max-width of 100% on everything.



I’ve seen that done on a feed-reader I used to have, it’s definitely possible (unfortunately the feed reader updated its behavior and doesn’t do it any more).



If people agree with that description, I can raise some bugs.





4)  I like your three SIZINGS… are these standard or you take?



My take, I was trying to think of the least confusing way of defining zooms!  Going by the thing you are making bigger seems to help. (Going by the user’s method of zoom is very confusing.)



Is it worth me writing it up a bit more into a blog post or wiki page somewhere?
