100% Sidebar Background Color

I’d created some ports of MovableType styles and had mentioned them on this support forum but I’m not exactly happy with them….

Please see:

Since the content div is larger, and footer is set to clear:both, The sidebar always ends before the content div ends(is shorter) and sadly, the right section loses consistency because the sidebar has a background, which the space beneath the sidebar doesn’t

I’d like to make sure that the entire right column has a gray background (something like the wordpress support forum)

Can someone tell me how to work this out? I don’t want to use the min-height feature because it still wont give a 100% sidebar (and wont be IE compatible). Also setting sidebar hight to 100% does nothing at all.

Appreciate tips.
