Set Page ID/Class for front end developers?

NFLtim

I am curious about being able to set a class or ID in the tag to allow our front end guys the ability to do targeted CSS. We have page types where setting page-level CSS may not be the answer.

For CSS syntax, think:
#news {background:red}
#players {background:blue}
#userprofile {background:yellow}
#userprofile .some-element {display:none;}

I thought about dropping in some jquery to wrap elements and set attributes, but this is not a predictable behaviour.
