attento che il DTD non va bene... devi usarne uno inferiore

codice:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Nuova pagina 2</title>
<style type="text/css">
<!--
body {
margin-top:0%;
margin-left: 0%;
margin-right: 0%;
margin-bottom: 0%;
}
-->
</style>
</head>

<body>

<table border="1" width="100%" cellspacing="0" cellpadding="0" height="100%" id="table1">
	<tr>
		<td width="20%" height="100%" bgcolor="#00FFFF"></td>
		<td width="80%" height="100%" bgcolor="#FF99CC"></td>
	</tr>
</table>

</body>

</html>
