Is there anyway to center all of the theme's content (header, body, and side bar) just based on the post column? This would move everything slightly to the right, without being entirely right justified. Here's a photoshop mockup.
Additionally.. Would there be a way to insert an image to the left of the content that stays fixed when scrolling? I'm trying to achieve this composition in a way that will look consistent across multiple screen resolutions.
I realize I'm asking a lot of questions, but any insight would be greatly appreciated. I'm really eager to get my site off the ground.
