I got some basic understanding about the "classes". As for the inspecting of elements, I'll need to learn how to decipher the techie stuff there. (I use Safari as I don't have Chrome).
For my education, help me understand: when I insert e.g. "man", "pan" into the Class box in Cornerstone, do I need to insert a comma after each of them? Also should I do it in the column, row or section or the specified Element, or all?
Also in my last para of my last post, what is z-index?
