Problem s layoutem a s menu

V IE se zobrazi vse v poradku ale kdyz si otevru stranku v jinem prohližeči tak no vidite samy dobre. S css sem zacal takze je me jasny ze to budu muset cely prekopat:(
zdrojoví kod layout:

body {
font-size:80%;
background-color:black;
font-family: Comic Sans MS,Arial,Verdena;
color: #818181;
text-align: center;
}

#all {
width:790px;
text-align: left;
margin: 0 auto;
}


a:link {color: #996633;
text-decoration:none;
text-align: none;
font-weight: normal;
}

a:visited{
color:#B9A999;
font-weight: 100;
}

a:active {
color:#B9A999;
font-weight: normal;
}

a:hover {
color: #C5863B;
text-decoration: underline;
font-weight: bold;
}

#hlavicka {
width:780px;
height: 130px;
position: relative;
margin:20px 0px 0px 0px ;
background-image: url("hlavicka.jpg");
}

#levy{
width: 200px;
position: absolute;
margin:0px 0px 0px 0px;
background-image: url("pozadi.gif")
text-align:center;
}



#obsah{
width: 580px;
height: 300px;
position: absolute;
margin:0px 0px 0px 200px;
padding: 20px;
background-image: url("pozadi1.gif");

}

#paticka
{
width: 580px;
height: 40px;
position: absolute;
padding: 10px 10px 10px 10px;
margin:305px 0px 0px 205px;
background-image: url("paticka.gif");
}
MENU:
ul {
list-style: none;
margin: 0;
padding: 0;
}


#menu {
width: 200px;
margin: 3px;
}

#menu li a {
height: 32px;
voice-family: Comis Sans MS;
text-decoration: none;
font-weight: normal;
}

#menu li a:link, #menu li a:visited {
color: #996633;
display: block;
background: url(menu.jpg) 0 0px;
padding: 8px 0 0 20px;
font-weight: 100;
}

#menu li a:hover {
color: #C5863B;
background: url(menu.jpg) 0 -32px;
padding: 10px 0 0 30px;
font-weight: bold;
}

#menu li a:active {
color: #B9A999;
background: url(menu.jpg) 0 -64px;
padding: 10px 0 0 35px;
}
