Recent discussions I've had with MS reveal that CSS support has been slated for future versions (no, I'm not saying "it's in Yukon," the sad, patent answer for all anybody ever wanted). RS doesn't support style templates of any sort out of the box - though I'm sure its do-able (with Time and Money anything is, as any consultant will confirm ... ).

Out-of-the-box features (such as width of selectors, etc.) cannot be modified without braving a "beyond the box" world - but that is the nature of "out-of-the-box."

The former (re: CSS) is a very intuitive question, however. Believe me, it occurred to me about three thousand times when I was doing beta of Reporting Services...
