I really have to register myself to w3 mailing lists because I
frequently have suggestions for you w3c people :)

http://stackoverflow.com/questions/16170010

this question made me think about a pseudo-state selector that would be
really useful

as opposed to :hover, :focus is enabled only on "target" element (not on
the whole parent tree of the focused element)
that's the same behavior with "onfocus" and "onblur" dom events, that
don't bubble up, as opposed to mouseover/out
but in dom we have also "focusin" and "focusout" that do bubble up

so, what about doing the same with css? like for example

div:contains-focus

thank you in advance, hoping to be helpful

Giorgio

an answer on stackoverflow question let me notice the existence of the
"selector subject"

so, this '#foo div:contains-focus'
would only be an alternative syntax to '#foo !div *:focus'
...I guess

anyway if user agents implementors decide to not implement the !subject
selector thing, it would be nice to have :contains-focus at least

thank you
