:hidden doesn't check for opacity: 0

[lonesomeday]

The logical way to prepare an element to be faded in using fadeIn is by setting the opacity style to 0. However, invoking is(':hidden') on an element with opacity 0 returns false, unless hidden by display: none.

It would be useful if the :hidden filter checked the opacity setting.

Technically, this is all correct - but I see the conundrum. Marking "needsreview" for further bike-shedding.

-1, It's exactly as documented. The element takes space and should be considered hidden.

[timmywil]

-1, It is not "hidden" if visibility: hidden either.

[paul.irish]

-1, that'd be more of an :invisible as the element still takes up space, just like with visibility:hidden

The dimensions == 0 check is expected by users nowadays.

-1, If we do opacity:0 then what about top:-10000px;left:-10000px as well? I don't think we can change the standard to visible to human eyeballs and the docs are already clear on this.

[lonesomeday]

I understand the reasoning for not having it as part of the hidden filter. Is there an argument for adding the check to the fadeIn/fadeOut/fadeToggle methods instead? That's the main utility I see this as having.

-1, Different semantics here.

[ajpiano]

-1, Unrealistic.
