Grazie in anticipo.

Posta anche il codice della pagina!

[dreadnaut]

la pagina sembra creata con il metodo delle colonne assolute. L'articolo dovrebbe chiarirti le idee

Quale è il codice della pagina?
Ho letto l'articolo ma cmq nn riesco a capire chi sono column-left e column-right nel file css ammesso che ci siano solo due colonne esplicitate.

aiuto...
