ciao raga!
Allora, sapevo che c'era qualche imperfezione (qualcosa di non proprio standard) e mancava qualcosina tipo gli alt nel tag image, ma mi ha davvero depresso l'analisi del w3c;
in particolare aiutatemi a capire perchè considera errori i valori dei margini del body e come dovrei fare per settarli!

codice:
[not Valid HTML 4.01 Transitional]

Line 58, column 17: there is no attribute "LEFTMARGIN"
<body leftmargin="0" rightmargin="0" marginwidth="0" marginheight="0" topmargin=

You have used the attribute named above in your document,
but the document type you are using does not support that
attribute for this element. This error is often caused by
incorrect use of the "Strict" document type with a document
that uses frames (e.g. you must use the "Transitional" 
document type to get the "target" attribute), or by using 
vendor proprietary extensions such as "marginheight" (this
is usually fixed by using CSS to achieve the desired effect
instead).......

Line 58, column 33: there is no attribute "RIGHTMARGIN"
<body leftmargin="0" rightmargin="0" marginwidth="0" marginheight="0" topmargin=

Line 58, column 49: there is no attribute "MARGINWIDTH"
<body leftmargin="0" rightmargin="0" marginwidth="0" marginheight="0" topmargin="0">

Line 58, column 66: there is no attribute "MARGINHEIGHT"
...n="0" rightmargin="0" marginwidth="0" marginheight="0" topmargin="0">

Line 58, column 80: there is no attribute "TOPMARGIN"
...width="0" marginheight="0" topmargin="0">
e questi ????? :master:
codice:
Line 74, column 60: there is no attribute "BACKGROUND"
<TD COLSPAN=2 ROWSPAN=3 valign="top" background="immagini/areariservata.jpg">

Line 82, column 92: there is no attribute "HEIGHT"
...llspacing="0" cellpadding="0" height="109" class="testo_notizie">
mi date qualche spiegazione ????
