[SOLVED] Putting Space Between Sidebars

Hi,
If I use both the right sidebar, and inner right sidebar, the only thing (I know) I can do to split them is put a borderline down the middle, if I take the border out it looks like 1 large sidebar. Is there a code I can use to put space between them, so the background shows through the middle and they look like seperate sidebars.

Hope that makes sense, had no idea what to enter in search to find the answer!

Thanks
