Problema lunghezza div

[marcello90]

Questo è il sito in questione...praticamente con Chrome non ho problemi, invece con IE il div contenitore cioe' quello che contiene il tutto è molto più lungo e non riesco a capire come mai.
Ecco il link del sito http://uploadjuve.altervista.org/Sito_gia/home.html

Questo e' il codice CSS incriminato:

#contenitore{ position:relative;
    z-index:0;
    behavior: url(ie-css3.htc);  
    background-color:white;
    color:yellow;
	height:1050;
	width:800;
	top:50px;
	
	
    
	 
	  }
	  
	  
#primo { position:relative;
left:140px; z-index:1;
    z-index:0; border: groove #FF3F00 0.3em;
    background-color:yellow;
    color:yellow;
	width:500; height:300;
	top:+110px;
	 margin:0 auto;
	  border-radius: 10px;}
	  
	  
	  
	  
	  #secondo { position:relative;
    z-index:0;
	left:-220;
     
    background-color:blue;
    color:yellow;
	width:309; height:80;
	top:-300px;
	 margin:0 auto;
	  border-radius: 10px;}
	  
	  
	  
	  
	  
	  #terzo { position:relative;
    z-index:0;
     border: solid white 0.3em;
