This seems unusual to me.  You really want to set display on all decendants of
#notification regardless of what they are?  I'm not enough of a CSS expert to
know if this is ok or not - just seems odd.  Maybe deserves a comment?  I see
elsewhere we sometimes do this to all chidlren - which makes more sense than all
descendants to me...

yes, this is what I want, but I can understand your concern, so I'll change it
to be more specific.
