Ciao gente, sto realizzando un sito web con i css. Al momento tutto bene, tranne un problema di visualizzazione del menù. Su FF ed Opera appare spostato a sx, mentre su IE appare, come dovrebbe, al centro, integrato col corpo dell'intero sito.

Codice css:
codice:
#chromemenu{
width: 760px;
background-color: #f0f0f0;
border-left: 1px solid #ccc;
border-right: 1px solid #ccc;
border-bottom: 1px solid #ccc;
}

#chromemenu:after{ /*Add margin between menu and rest of content in Firefox*/
content: "."; 
display: block; 
height: 0; 
clear: both; 
visibility: hidden;
}

#chromemenu ul{
width: 100%;
margin-left: 0;
padding-left: 0;
margin: 0;
float: left;
font: bold 12px Verdana;
}


#chromemenu ul li{
display: inline;
}


#chromemenu ul li a{
float: left;
color: #004e90;
font-weight: bold;
padding: 6px 12px 6px 7px;
text-decoration: none;
}

#chromemenu ul li a:hover{
color: #df0007;
}
