Usunięcie marginesów

Kilka szczegółów o moim forum i stylu, z którym mam problem:
nazwa stylu: Default Rounded
wersja skryptu MyBB: 1.4.11
adres forum: niepotrzebne (styl dostępny tylko dla adminów)
opis problemu:

Otóż zainstalowałem sobie Default Rounded oraz dodałem na górze logo i gradient oraz zmieniłem tło forum.

Pojawiły się denerwujące marginesy:

Jak mogę je usunąć?

Oto global.css:

Odświeżam.

Spróbuj do body dopisać margin: 0;.
