I'm currently modifying the classic theme, I would build my own but time constraints have gotten the better of me.
Anyway, at the moment the sidebar code is something like #menu, #menu ul, #menu ul ul, etc etc, as you know, the classic theme in its default state.
However I want each individual widget to be in its own block. A single box with transparent space between itself and the next one. That would require a ul acting as a spacer.
I examined sidebar.php and widgets.php and I must say, I'm stumped. I can't seem to add or take away any ul or li tags to create the necessary spacer. Obviously I'm missing a fundamental mechanism that powers wordpress.
So how is it done, how do I add extra classes and ID tags to wordpress, notably the sidebar?
