[SOLVED] Space between Header and Body

hi everybody,

i know it's not a new subject, but i couldn't solve my issue reading the previous threads

i'm becoming desperate trying to eliminate the space between header and body in this website prototype:

i think i've set padding to 0 in every spot i could find, but still nothing!

any help would be very, very appreciated!

bye
