CMS How do I make a 300 px Adsense Ad Widget fit into a 300 px Sidebar?
 

For my homepage I've got my grid laid out for one left hand content column and a 300 px right hand column. But a 300 by 250 Adsense ad doesn't fit inside the Widget, it hangs over the far right border of the widget.

I found some Stylevars that effect the widget padding, but even with that padding set at zero the 300 px ad is too large for the widget.

On my forum blocks, I just edited forum_sidebar_width and this fixed the problem there. I just can't find the way to do it in the CMS pages.
