As a very new WP user, I was feeling pretty good that I managed to move the header in twentytwelve (to above the menu).
I then learned about child themes and the importance of. (Man could I go on about that. Ridiculous in this day and age that you have to muck around like that. Software exists to make life easier! There should be one button to press, and that's it!)
But anyway........So I started from scracth (with a fresh twentytwelve theme) and I managed to learn and successfully implement a child theme. Yay!
But I now have no idea where to go to do the header change. All the things (in css world) that were there when I was playing in the main twenty twelve theme don't seem to be around anymore?
