I'm trying to do several things to the widgets in the left-sidebar of my wordpress site. (I'm using a customizable version of the Able Theme.) First, I'd like to change the font size of the headings for the widgets, especially the image gallery widget. Second, I'd like to reduce the amount of space between the "Like us on Facebook" widget and the "Follow us on Twitter" widget. I've searched the forums, and even added some of the code you recommended in previous posts to my custom CSS box, but nothing's changing.
The blog I need help with is rachelmattson.wordpress.com.
