RE: Popup SC need comments

I agree with Jim that visible is already used several times in WCAG 2.0, so giving a definition here would complicate the whole document.

Using obscure is okay, but is it needed if only used once?  Does it raise more questions than it answers (e.g. what if part of the trigger is not in the screen space, or what is meant by perceive)?  I’m just playing devil’s advocate.  Unless we’re talking about popups with non-zero opacity, invisible is probably fine if visible is fine.

Hi Jim, Stephen, and all,

With this rendition do we need definitions for "visible" and "invisible"?

At one point we used the word "obscure". UAAG's definition is:

"To render a visual element in the same screen space as a second
visual element in a way that prevents the second visual element from
being visually perceived."
https://www.w3.org/TR/UAAG20/#def-obscure


I like obscure. After fiddling/editing a bit, seems "obscure" works only for TRIGGER. Only edit Trigger bullet.  I looked in WCAG20, where 'visible' is used 5 times. It is never defined. Don't think we need to define it.

edited version
Popup Interference: Except where popup presentation is controlled by the user agent, all of the following are true when popup content is visible:

•       Trigger: Popup content does not obscure any part of its triggering content.

•       Hover: If a popup is triggered via pointer hover, then the pointer may be moved onto the popup content without loss of visibility.

•       Focus: Popup content remains visible while any of its components, including the trigger, have focus.

Where we define popup as " becomes visible only on pointer hover or focus”.

It would be nice to get the readability level down a bit more but we
could work on that later.

Kindest Regards,
