styling the registration page form elements & layout

Hi ??

I’m having big problems trying to do even the most simple modifications to the layout of the registration page form. I’m using the CIMY Extra fields plugin so a couple more fields are present.

It seems tough to even put the labels above the text boxes instead of to the left of them. Would anyone have any ideas?
