[fixed] make tropo site-skinned pages wider?

[runpunkrun]

I used to have a userstyle that made the content on Tropospherical site-skinned pages wider but after the recent site changes it no longer works and I haven't been able to fix it.

I just want the entry content and comments to take up more of the page instead of being huddled together in a narrow column. Help with css?

Edit: Okay I dug around in the comments of the most recent dw-maintence post and found some code from darjeeling that did the trick.
