first of all: Thematic is a fantastic theme. Thanks for that.
Now to my small issue:
I'm trying to add a border (1px solid #ccc) to the sidebar, but not only to #primary, which looks bad if on the front page I scroll down and the sidebar is out of the picture, hence the border ends where the sidebar ends. I want a fixed static border between #container and the right sidebar. I tried adding a border-right to #container, but then, e.g. on the about me page, where i havent added much text, the border only goes as far as the content does of the page. And that doesn't look nice on the sidebar, since that will go down furher than the content of the page.
So, how can I add a fixed static border that will always start from the top and go down all the way to the bottom?
