122979 - :hover color and background attributes aren't inherited correctly

Status: VERIFIED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[Jens-Erik Weber]

I have defined background and color for a:hover in a CSS.
Then there is a <div class="box"> with overwritten background and color
attributes for a:link and a:visited, while the color & background for a:hover
and a:active are not overwritten, so they should have the general assigned
values, i.e. the colours of the link should change, but they don't in Mozilla
0.97 for Linux and Windows, in Opera 6.0 TP 1 they do.

If you don't assign any of the values for "box a:link", "box a:visited", "box
a:hover" and "box a:active", the general assigned values apply and work
correctly. See 2nd alternate stylesheet in my testcase.

If you assign all of the values for "box a:link", "box a:visited", "box a:hover"
and "box a:active", then these overwritten values apply and work correctly. See
3rd alternate stylesheet in my testcase.

But overwriting only "box a:link", "box a:visited" without overwriting "box
a:hover" and "box a:active" doesn't work. I haven't tried other combinations
(and I don't have time for it).

That's because hover is not currently hierarchical

Why is this a duplicate.  Rather...

... it's INVALID.  The selector ".box a:link" has higher specificity than any
a:hover so it overrides it.  MSIE has incorrect behavior where it doesn't treat
selectors with :hover according to the normal specificity rules.

Reporter, CSS2 spec
http://www.w3.org/TR/REC-CSS2/selector.html#dynamic-pseudo-classes says:

"Note that the A:hover must be placed after the A:link and A:visited rules,
since otherwise the cascading rules will hide the 'color' property of the
A:hover rule."

Also hover.css has an error at line 11.
