You can see what I'm discussing here: http://www.craigatkinson.co.uk/category/news
as you can see, the text trails to the end of the page. What I would like is for the text to sit within a space of about 600px. I tend to use 700px wide images in posts and would like the post text to come just short of the image.
I can't set the blog to a max width because by doing that the left sidebar will no longer be flush with the left of the window.
Is there a way I can do this?
