Scusate se vi disturbo ancora con cose banali, stavo risistemando il CSS del mio file quando per sbaglio ho cancellato un pezzo e... Non riesco più a ricentrare il contenuto! E' sotto i menù a sinistra 
per come cerco di farlo andare da altre parti, non si muove.
Codice pagina:
<!DOCTYPE 99/xhtml">
<head>
<title>Linguaggio Editoriale</title>
<lik hr="style.css" rel="stylesheet" type="text/css" />
<lik re="stylesheet" type="text/css" media="print" href=
"style_stampa.css" />
<meta http-equiv="Content-Type" content=
"text/html; charset=us-ascii" />
<script type="text/javascript" src="script/cercaPagina.js">
</script>
<script type="text/javascript" src="script/stampa.js"></script>
<script type="text/javascript" src="script/galleria.js"></script>
<script type="text/javascript">
<!--
function in_giorni (s) {
return Math.floor(s/(1000 * 60 * 60 * 24))
}
//-->
</script>
</head>
<body>
<div>
<div id="logo">
<i src="" width="727" height="240" alt=""/>
</div>
<div id="navbg">
<div id="nav">
<p>menu<p><a h="javascript:stampa()">Stampa la pagina</a></p>
</div>
<div id="contentbg">
<div id="content">
...contenuti
</div>
</div>
</div>
<div id="spacer">
<script type="text/javascript" id="data">
<!--
var adesso = new Date( );
document.write("oggi è il " + adesso + "<br/>");
//-->
</script>
</div>
<div id="spacer2"></div>
</div>
</body>
</html>

Grazie in anticipo! 
grazie ancora e un salutone!
ora ho corretto ma l'errore persiste:
