OK, I'm sure this question has been asked a zillion times before but I can't find what I'm looking for in the forums - apologies if I've missed the obvious!
I'm trying out Moodle within our school at the moment and want to simplify the front screen and customize using a theme. I'm happy to fiddle with CSS, HTML and PHP but I'm struggling to find a guide to creating themes. I'm really looking for the structure Moodle uses. Any help gratefully received!
