Editing Sidebar

The MiddleEarth theme is absolutely amazing! To suit my purposes, though, I would like to make one small modification.

Is it possible to make the right sidebar a little less wide so that the main container has more room for content? In the CSS file I didn't see a right sidebar property that would control it (I'm not even sure it's in a container).

Many thanks!

Hi!
You need to edit option width in the section .sidebar.right in the css/wide.css
