This should be a quick and easy job.
My blog: [url removed, login to view]
All I need is for the left sidebar, which is currently at a width of 100, to be made into a width of 160 (allowing space for advertisement).
My main concern is that neither of the sidebars, nor the middle content section, spill over into the other. This should be browser-compatible with IE, Firefox, and Safari.
The width of the entire page will need to be stretched accordingly. I do not want the middle content or right sidebar to be cut in width.
