I haven’t edited so to speak anything…..just used the program to build my site. I haven’t done anything to the style css file. From what I have read and understood is that if I make my edits or build off of the active theme I guess you would call it, that when an upgrade is applied I will lose all of my specific input info. So it advised making all your changes from a child Theme that way the Parent is what is getting updated not your child. Now thats how I understand it, but I’m a noob to this. I build computers. I don’t program them..:)
