I did a CSS magic trick and broke my enrollment button

hey folks, so on easterntemptations.co.za, for which, incidentally, you have administrative access... i magically made the front page's mailchimp enrollment form button disappear.

i paste the code in, the code for the button is there, but under no circumstances will the @@@@ appear in public.

I've spent about 3 hours looking for my wrong incantations, checked my grimmoires and before i rip out my ouija board, will someone please be Harry Dresden and go check what I did?
