Elppa, maybe next time include ID's/classes in your div example because although "div > div" certainly is legal, it could be dangerous to use that example in a real site as some newbies would, affecting any div within another - what a potential mess. Using ID's/classes also helps newbies and guru's alike when debugging style issues, plus extremely useful if tied into Javascript methods.
Yep, I admit fully I am being picky here. My apologies for that, but of course nothing personal intended and of course your advice was spot on, as always.
Cheers to you, please don't kill me for this.
