Dann machst Du was anderes falsch!
Hast einen Link?Der ganze Code (vor allem dein CSS) würde wahrscheinlich beim Lösen des Problems ganz gut helfen.
mal sehen:
<body>
<div id="all">
<div id="header"></div>
<div id="main">
<div id="menu">
<div id="mainmenu"></div>
<div id="submenu"></div>
<div id="content">
<div id="cont"></div>
</div>
<div id="bottom"></div>
</div>
</body>
css:
body {
margin:0px;
padding:0px;
font-size:11px;
font-family:"Tahoma", Arial, sans-serif;
line-height:140%;
background-image:url(images/site/content/main_bg.jpg);
background-repeat:repeat-x;
background-color:#E3EDF6;
}
#all {
width:934px;
height:auto;
position:absolute;
left:50%;
margin-left:-500px;
}
#header {
width:934px;
height:253px;
background-image:url(images/site/content/header.jpg);
background-repeat:no-repeat;
}
#main {
width:934px;
height:auto;
background-image:url(images/site/content/center_bg.jpg);
background-repeat:repeat-y;
}
/* ----- MENU ----- */
#menu {
width:326px;
height:410px;
background-image:url(images/site/content/menu.jpg);
background-repeat:no-repeat;
float:left
}
/* ----- CONTENT ----- */
#content {
width:608px;
height:410px;
background-image:url(images/site/content/content.jpg);
background-repeat:no-repeat;
float:left
}
#cont {
position:relative;
top:auto;
left:auto;
z-index:1;
width:500px;
height:auto;
margin:25px 0px 0px 45px;
}
/* ----- BOTTOM ----- */
#bottom {
width:934px;
height:146px;
margin-top:-52px;
background-image:url(images/site/content/bottom.jpg);
background-repeat:no-repeat;
clear:both
}
die bilder sind ja erstmal unwesentlich.
