Div absolute

[galateo76]

Ciao Ragazzi, ho cercato ma non ho trovato...forse non ho cercato bene ma spero possiate aiutarmi. Ho creato un layout con photoshop e poi con un tool gratuito in rete ho trasformato tutto il codice. Il tool mi trasforma tutti i livelli in div posizione assoluta. come faccio a centrarli in mezzo alla pagina tutti in una sola volta affinchè a qualsiasi risoluzione posso vedere centrato il mio layout? allego il css

  font-size: small;
