I understand the purpose of the child theme, but for what I am wanting to do, i.e. unsnarl all the options from one another, it seems as though this is counter to my purpose.
I do not want to add yet more options and divs. I want to narrow down the massive list of things I am not using so that I can better understand what code goes to what option.
Is it feasible to make a copy of the Twenty Eleven theme, name it something else, and use it to chop things out of, thus leaving an unsullied Twenty Eleven in case I botch it?
