Yoast Breadcrumbs

Folks, Sorry for asking so many questions about my news implementation of Clean Business Pro, but it's new and I'm trying to find my way with new features. I very much like the "look and feel" of this new theme. 1. What's the best way to implement Yoast Breadcrumbs? Do I need to insert CSS into one of the files? A new child-theme (which I don't know how to do). After doing research, I am using Breadcrumb NavXT, which your themes support. But if I add a widget before the content, widget is much too high-approximately 3 or 4 lines high when we only need 1 or 2. So I have now have the widget at the top of the sidebar. If I could size the before-content widget, my problem might be fixed. But maybe Yoast Breadcrumbs is the better way. 2. How do I get my office address to show in the Google Map option? Thanks, Ed
