Salve a tutti ho un problema, praticamente nel mio foglio di stile se non imposto nella classe .content la proprietà height con un valore fisso (es 450 px) succede che cambiando pagina il sito che dovrebbe trovarsi sempre nella stessa posizione si sposta di qualche pixel verso destra.
Forse è questione di bordi padding e margini? Li ho azzerati ma succede sempre la stessa cosa.
Qualcuno puo' dirmi cosa succede e dove sbaglio?

Grazie mille in anticipo.
