plain white blog sidebar with no frame?
 

How to I edit just the blog sidebar.

I want the background white or transparent with no outer frame.

I see I can get mostly there with the style vars on Sidebar but that also affect the Forum sidebar... which actually doesn't bother me too much.

The main thing is the shadow on the sidebar. Seems I can only get it with Global_shadow, but that also strangely gets rid of the frame around the blog search text box, so that you can't see where to enter text.

How do I eliminate the shadow just on the sidebar without losing the text box?

Thanks.
