Pogięło cię, człowieku?
Firefox + Firebug albo jakaś nowa Opera. Nawet IE8 ma sprawdzanie elementów...

Że co niby? Może jaśniej???

Co kurde jaśniej? Załączyłeś samego CSS bez linijki HTML-a. Skąd mamy wiedzieć gdzie jest Forum, a gdzie grafiki belki...
Poza tym jak już pisałem - gdy używasz FF, to możesz kliknąć prawym na dowolnym elemencie i (jesli masz zainstalowanego Firebuga) możesz wybrać "zbadaj element" - pojawi ci się cały CSS dla tego elementu. Możesz sobie go dowolnie na bieżąco zmieniać.
Opera ma jeszcze większe możliwości. A opcja za to odpowiedzialna nazywa się 'Przegląd elementu'. W IE8 jest to bardziej ukryte (F12) i gorsze w obsłudze, ale też się da to zrobić...
