Yes, situations where a user can't turn the screen sideways (for instance, because they use a tablet that's solidly mounted in one particular orientation and attached to their powered wheelchair)...but I see you mention it later in your email: > One I can think of is a person With a physical disability who has his > tablet mounted in one direction, and if he goes to a page that forces > him in other orientation then he can’t turn it. > But it seems to me that > this is already true for many apps and they are causing a problem, which WCAG currently doesn't have any SCs to tackle it with. > and I haven’t seen any websites that > only work in landscape. They're out there. For a sampling, see https://www.google.co.uk/search?q="please+turn+your+device" Many sites currently do this sort of thing in a very primitive way (they check the browser window/viewport width/height and, if it's not in the "correct" ratio, they simply put a big roadblock in front of the content until the user changes the ratio/turns the device. As noted earlier in this thread, there are now more robust standards/techniques coming (screen orientation API, CSS directives that lock a view into a particular orientation, directives in progressive web app JSON manifests that explicitly set a locked orientation). And again, WCAG currently doesn't have the tools to flag this as a problem. P -- Patrick H.
