I'm using the Living OS Upsilon theme on my blog. I'd like to hack the theme & widen the post display area. I'd like to dramatically reduce the amt. of blank blue space on the right & left side of the page. I know how to widen the dimensions of the post display area. But how do I reduce the amt. of blue space on the pg? And do it so that all the segments (sidebar, banner, etc.) line up properly?
