hi i am in the process of designing a new website for myself. I reguarly test it in both IE and Firefox. How i want it to appear is in IE but I can't get it to look the same in Firefox. The screenshots and CSS are below. Thanks in advance

body {
background-color: #CCCCCC;
font-family: Arial, Helvetica, sans-serif;
color: black;
font-size: 16px;
margin: auto;
}
#pagecontents {
background-color: white;
width: 735px;
border: 1px inset gray;
margin: auto;
} 
#content {
width: 735px;
float: right;
margin: 2px;
}
