Re: Issue 650 Does the Hover or focus SC apply to tabbed interfaces?

What’s a “finger tab”? I agree re input help text, but that is content that should meet this SC, right? Whether aria is used or not has no bearing on the SC – ARIA provides a technique to satisfy this SC, but isn’t  directly a factor.

For a set of tabs that uses the tab key to change the tab, that might be a problem, but does seem to hinge on the “additional content” definition.

​

@andrew, not with finger tabs, not with input help text appearing on focus (instead of a info popup) and not with tabs implemented WITHOUT ARIA and/or still using the Tab key for navigation ​in contrast to​ arrow keys.

I still think that since the content change occurs on selection and not on focus, this SC doesn’t come into play.

Selection is different from focus: https://www.w3.org/TR/wai-aria-1.1/#aria-selected

When going back to the roots, isn't this SC not totally based on content "blocking" other content by "floating" over that other content, causing problems understanding the information/relationship AND, especially when zoomed in, the 'floating' content disappearing when moving the mouse trying to read the floating content which is not in view?

By "floating" I mean all variations of tooltips, pop-overs, pop-outs, pop-ups, floating menu's etc. often caused by absolute positioned / z-index CSS.

If so, is this SC also necessary when this type of exposing information is not used?
We can as easily NOT use a pop-over / floating but show the information 'in-page' (pushing back the content a bit to reveal the "additional content"). We see this for instance when the focus is on an input field and showing help text beneath it. The help text, per field, is only visible on-focus.

I guess not, and, as this is also the case for tabs / finger tabs (not floating over other content) we could search for a way to have this SC only apply to the "floating part"...​

Agree with David about drawing a bright line and to clearly define the distinction.
The "Dismissable" sentence is not achievable for ARIA tabs and also for the similar finger tabs concept.

First thing I've tried was searching for the definition of "additional content" and couldn't find it.
It puts the term in a grey area which makes assumptions unfounded.

I see there's a definition for "supplemental content" which is "additional content that illustrates or clarifies the primary content". So if I put clarifying content for the primary content in a Tab structure with- or even without using ARIA, add it to a custom tooltip or using "finger tabs" which is very similar to ARIA tabs, that's a design choice based on the amount of information and aesthetics. As supplemental content is a subset of additional content you can't state:

"A tab set switches content, it doesn’t show additional content."

We "hide" supplemental/additional content in finger tabs to saved screen space and only load it when hovering or focus is on a finger tab. So it's not there on page load and you can't "dismiss" the finger tab content panel. The loading is also a developer choice, not a predetermined given.​

Maybe I'm missing something... I don't know how that would fix it. The only way that I can see being able to close a popup without "moving the pointer" or "without having to move the pointer" is by pressing the "esc" key, in which case it seems we are saying that it can be dismissed without use of the pointer??

I do think the line "dismiss the additional content without moving pointer hover or keyboard focus" is weird, because the user has to move the pointer to hit the "x" ... how would a mouse user dismiss a popup without moving the mouse?
