Grazie della disponibilità,

questo è il codice che validato su: http://validator.w3.org/ rimanda 8 errori,
chiari quelli attribuiti ai font che con xhtml non devo dichiarare qui, ma nei css.
Poco chiari sia quello della chiamata al <link href="Principale.css" rel="stylesheet" type="text/css"/>
che quella del tag [img]images/Logo.gif[/img]
