What is it?
This Pseudo-class applies to content that is scrolled in a visual rendering environment.
Example
Ext/Doc: body :scrolled-content
{ background-color: red }
(apply a red background to scrollable elements inside the BODY element.
In-Line: NA
Browser Peculiarities
Remember that the BODY element is itself scrollable, so if you
just say ":scrolled-content" as a selector, it will apply it to
the whole document canvas. To specify this pseudo-class for all
OTHER scrollable areas, use "body :scrolled-content" (Descendent selectors.)
Netscape 6 applies this to the SELECT element contents, but not
to TEXTAREA elements. I find that odd. 8-}
