Another Browser Compatibility Issue

[cgermain]

I'm using CSS for my web site (which is currently haphazard) http://www.wanttobevagabond.com The site shows up and functions correctly in Firefox, but is missing images and misaligned in IE (of course). I'm guessing it has to do with a small CSS tweak, but I don't know what that tweak is. I also have some Java script in there that calls a random banner image. Any help would be greatly appreciated.
You can view the main code at the page. The Stylesheet is below:

/* CSS Document */

html, body, ul, ol, li, p, h1, h2, h3, h4, h5, h6, form, fieldset {

padding: 0;
border: 0;

body{
background-color:#99CCCC;
color:#000000;
font-family:Verdana, Arial, Helvetica, sans-serif;
margin: 0;
padding: 0;
text-align: center;
}

/* Layout Divs */

#wrapper{

margin:10px auto;
border: outset 1px solid #000000;

#nav{

text-align: center;

}


#content p{
margin: 10px;
}

#footer{

}


/* Font Styles */

Ok thanks, that worked, but I still have an error in IE. Every other time I load the page in IE it says, "Internet Explorer cannot load page. Operation Aborted." I've included the CSS menu code below which might be causing it???

.chromestyle{
width: 99%;
font-weight: bold;
}

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

.chromestyle ul{
border: 1px solid #BBB;
width: 100%;
background: url(chromebg.gif) center center repeat-x; /*THEME CHANGE HERE*/
padding: 4px 0;
margin: 0;
text-align: left; /*set value to "left", "center", or "right"*/
}

.chromestyle ul li{
display: inline;
}

.chromestyle ul li a{
color: #494949;
padding: 4px 7px;
margin: 0;
text-decoration: none;
border-right: 1px solid #DADADA;
}

.chromestyle ul li a:hover, .chromestyle ul li a.selected{ /*script dynamically adds a class of "selected" to the current active menu item*/
background: url(chromebg-over.gif) center center repeat-x; /*THEME CHANGE HERE*/
}

/* ######### Style for Drop Down Menu ######### */

.dropmenudiv{
position:absolute;
top: 0;
border: 1px solid #BBB; /*THEME CHANGE HERE*/
border-bottom-width: 0;
font:normal 12px Verdana;
line-height:18px;
z-index:100;
background-color: white;
width: 200px;
visibility: hidden;
filter: progid:DXImageTransform.Microsoft.Shadow(color=#CACACA,direction=135,strength=4); /*Add Shadow in IE. Remove if desired*/
}


.dropmenudiv a{
width: auto;
display: block;
text-indent: 3px;
border-bottom: 1px solid #BBB; /*THEME CHANGE HERE*/
padding: 2px 0;
text-decoration: none;
font-weight: bold;
color: black;
}

* html .dropmenudiv a{ /*IE only hack*/
width: 100%;
}

.dropmenudiv a:hover{ /*THEME CHANGE HERE*/
background-color: #F0F0F0;
}
