Description Andrey Botalov 2014-03-27 20:55:15 UTC 
Let's say there is element:
<span style="border-style:solid;border-width:5px;"></span>

This element has 0 clientWidth and clientHeight but its offsetWidth and offsetHeight are positive numbers.

The spec currently says:
"The element must have a height and width greater than 0px" without saying type of width/height.


I made a quick test and the following element is clickable in Google Chrome:
<span style="border-style:solid;border-width:5px;" onclick="console.log(1000)"></span>

I think it should be clarified which type of width/height is meant.

I'll work on getting visibility experts' attention.

The newly added

"The element must have a DOMRect height and a DOMRect width greater than 0px, as returned by element.getBoundingClientRect() , unless the element has a descendent with a positive height and width."

does not mention which elements MUST/SHOULD/MAY be (considered) displayed.

Also it is a slower check (descendents are involved) and some trivial checks go first in this algorithm. It makes sense to move all the trivial checks up.

Also I noticed that "displayed" is used in most of the section while "shown" or "visible" on only a few occasions.

I removed "if Javascript is enabled", too ( https://www.w3.org/Bugs/Public/show_bug.cgi?id=25681 )

I just attached a patch I suggest committing.

There is an extra space between "element." and "getBoundingClientRect()" now.
