first of all I want to say that I really like your theme!
Now to the issue; I would like to know how I can reduce the gap between the content and the sidebar and assign the extra space either to the sidebar or to the content. So far, I've only been able to reduce the gap by lowering the right margin for the content in the CSS stylesheet. However, this only shifts the sidebar and the content closer together producing a gap to the right of the sidebar. So, could you provide me with the code necessary to reduce the gap between these two elements while reassigning the extra space, say, to the sidebar.
