Re: CFC: Target Size and Target Size (no exception) SC

Hi


I think we need to keep in mind that we want 2.1 to be required - not just “good if you can do this”

for that to be true (for that to happen) we need to be sure that 2.1 CAN be applied on ALL sites.


If we do,  then the question isnt if it works on one page per site 
or even if it works on MOST sites

the question is    Will it work on ALL sites. 

and for ANY site that it doesn’t work
can we figure out why it won’t work - and make that an exception
OR
do we want to say that that site just won’t be able to conform.


We need to remember that:
We can’t create a rule — that we want everyone to follow on every page (or we want people to REQUIRE for every page —  unless we know that everyone CAN follow it on EVERY page.
otherwise we need to just have it be advice

Unfortunately  we can’t have it both ways.   (i.e. it doesn’t work EVERYWHERE but we want it to be REQUIRED) 

so the test is never "I can show where it works"
 (if we want people to require 2.1 SC)  the test has to be  “no one can find a page where it doesn’t work (given our exceptions)"

So they may be a fair representation of the site owners that are ether required by law to meet WCAG (or derivatives of WCAG).

So small screen touch devices go into a mode that adds horizontal scrolling when enlarged.  So you are suggesting that it’s ok for users to have to initiate a pinch zoom, then scroll the screen and then tap the target in order to get a target that is large enough for them.  I don’t think this is very practical.
