Gespaa Theme trouble

Hello I’ve been trying to modify the Gespaa theme so that it is wider.

I managed to be semi-successful in this, as resizing the width, wrapper, header, and left content area worked.

The left content area I put around 700px, and the right sidebar got pushed down. I was playing around with the sidebar settings in style.css, and eventually after setting the width and margin around 500, it worked again. However, there’s now a huge gap between the sidebar and right side, and part of it goes into the left content area.

If anyone can help, it would be greatly appreciated.
