Hi - this is great!
So I looked at the source code and found all these classes (I should have started there).
I can style .otw-sidebar and give it a background color. I can style .otw-sidebar-1 h2.widgettitle and effectively style the headings.
But then I noticed that each widget has a different name ".otw-widget-1", ".otw-widget-2" etc. I tried various things. When I try to style .widget .otw-widget, nothing happens. When I try to style .otw-widget, nothing happens. When I try to style .widget .otw-widget ul li, nothing happens.
Should they be styled by .otw-widget, or using ul li? What am I doing wrong?
Thanks for the help and great plugin!
