salve, vorrei impostare il mio sfondo in modo che si adatti a qualsiasi risoluzione. Ho costruito il mio template con artisteer, e uso wordpress per gestire il mio sito...nn ho molta conoscenza sul campo dell'informatica ...Finora ho provato a modificare il css e l'html seguendo le istruzioni di alcuni siti ma niente(lo sfondo rimane bianco). Vi lascio i codici sperando mi possiate dare una mano

CSS:
body

{

margin:0;

padding:0;

width:100%;

height:100%;

overflow:hidden;

}

#background

{
position:absolute;

width:100%;

height:100%;

}

header.php (wordpress):
