How to achieve a certain padded two column layout with Blueprint?
===

I wish to adapt a simple ASP.NET MVC view to a two-column layout. To that end, I figured I'd use Blueprint, but I'm not sure how to retain the desired page design within the grid. The below screenshot shows the page as laid out by Blueprint.

What's missing from the original design is margins (30 px) to the sides of the white box in the middle, in order to create space around the content. How can I replicate these margins while using the Blueprint grid?

Also, I'm wondering how I can achieve a liquid layout (the original design is liquid) with Blueprint?
