Menu works great in firefox but IE7 or IE8 doesn't work

I have created a beautiful vertical menu that works great in FireFox but doesn't work in IE7 or IE8 so not sure what is the cause.  Here is the code below
<html>
<head>
<style type="text/css">
body {
	margin:0px;
	padding:0px;
	background:#555555;
}
.innerMenu {
	margin-top:20px;
}
ul.innerMenu li {
	font-size:13px;
	width:170px;
	height:25px;
	color:#fff;
	font-weight:normal;
	list-style:none;
	background:url(/images/myarrow.png) right top no-repeat;
}
ul.innerMenu li:hover {
	width:170px;
	height:25px;
	background:#252525 url(/images/myarrow.png) right top no-repeat;
}
ul.innerMenu li:hover .subMenu {
	left:200px;
	top:auto;
	top:20px;
}
.submenu li {
	width:165px;
	height:30px;
	padding:5px;
}
.submenu li:hover {
	width:165px;
	height:30px;
	padding:5px;
}
.innerMenu li a:link {
	color:#fff;
	text-decoration:none;
}
.innerMenu li a:visited {
	color:#fff;
}
.innerMenu li a:hover {
	background:#252525;
}
.subMenu {
	float: left;
	left: -999em;/* Hide Div layers */
	margin: 0px auto;
	position: absolute;
	text-align: left;
}
</style>
</head>
<body>
<!--Start menu -->
<ul class="innerMenu">
  <li><a href="#">Main Item 1</a>
    <div class='submenu'>
      <ul>
        <li><a href="#">Item2</a></li>

      </ul>
    </div>

Add a strict doctype to your page, and work from there.
That way most browsers will all show the same.


For example add above your <html> tag:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

Open in new window

or
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
