I'm working with a child theme of twentyeleven. I want to add a customer footer with a sitemap in it. I've tried footer sitemap for this, but it's not giving me what I want. My question is, is there a plugin to add extra divs to a theme? If not, what is the easiest way to achieve what I want? Do I have to go into the PHP, because I'd prefer not to as I am not extremely familiar with PHP.
