Lunghezza DIV

[GANDULE]

Uhm... ho provato... ma... non và.
Posto il codice, magari può chiarire qualcosa...

body
    {
        background: transparent url(Images/BackGround.jpg);
    }
    
    
img
    {
        border: none;
        
        width:1024;
        height:430;
        
    }

    

#div_container
    {
        height: 700px;
        width:auto;
        
        margin: 0px;
        padding: 0px;
    }
    
    
#div_menu
    {
        height: 80px;
        width: auto;
        
        background-color:#000;
        
        padding: 0px;
        margin: 0px auto;


    }

        background-image: url(Images/Bottoni/backMenu.jpg);
        background-repeat: no-repeat;
        
        
        height: 80px;
        width: 1024px;
    
        margin-left: auto;
        margin-right: auto;
    }
