I am using a lightly-modified version of the Blue Zinfandel theme on my site http://www.word-detective.com. As you can see, each post has Adsense code at the end. The center column is 478 px wide, the text margins 440 px wide. At the moment, I can only fit 234 x 60 text ads there, but I'd like to fit 468 x 60 image ads there. The margins/padding screw that up.
Is there a way to keep the margins as-is for text and somehow turn off the margins around the ad code? Or is there a better way to fiddle with the width of the center column without screwing up the page layout?
Thanks for any help.
