just to clarify - this was intended as a note to:
1) highlight the use of a descendent selector
2) suggest that the use of a descendent selector shouldn't be a reason to reject or take other action on this commit because we already have so many in the code that the next step is a full re-factor i believe.
3) note that i have also been slipping and using them in this particular css file because they're already so many of them there.
