never mind on last post i have decided not to use child theme as it appears that css and html is required, and since i don't know that I will just keep Responsive on it's own.
question:
1. .if you have a theme, and you want to change it can you keep the theme loaded deactivate it, and then download another theme and activate it, will it switch over, and then if you don't like it reverse process to go back to original, and will work be lost?
thank you, Carol
