I'm new to concrete5 and I won't hide that I'm a much bigger fan of the dirty hands-on coding approach. Unfortunately I'm not making this site for myself, but for a friend, so a CMS is difinately a must, and when it comes to content management systems, I've always thought of concrete5 as the best, by far. I've been playing around with it for a couple of days and I'm desperately looking for a kind of back end, or way to overrule the basic structure of the sites (I guess it's the template that's responsible for that?). For this specific matter it's the auto nav i would like to extent across all three top areas, instead of just having it in the middle and. With no margin to the top. But generally i can't help but think that there must be some kind of way to overrule these premade structural guidelines - or change them at least. I was convinced it was done with themes so I've tried changing the theme a couple of times and didn't really see any changes at all. Would someone maybe point me in the direction of what i could be looking for?
