On my static home page, the client wants the borders between all columns to be dotted instead of solid. I changed the border between the left sidebar (the nav bar) and the middle div to dotted, but can't figure out where to change the style of the border between the two columns within the middle div. (See http://www.bookbuilders.org/wordpress/).
Where would I change that setting? I am familiar with CSS and do work in the styles.css and header.php, but it would, of course, be simpler to change it in the Theme Options panel, if possible.
Thanks in advance,
Spencer
