Non mi convalida il css ne' lXhtml ecco i seguenti errori:
XHTML
# Error Line 78 column 43: document type does not allow element "span" here; assuming missing "li" start-tag.

...n style="text-decoration: underline;"><span style="font-weight: bold;">



# Error Line 81 column 4: end tag for "li" omitted, but OMITTAG NO was specified.
[/list]

You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".

Che fare?

CSS:
* Line : 2 (Level : 1) You have no color with your background-color : body
* Line : 18 (Level : 1) You have no color with your background-color : #wrapper

NON CAPISCO:::

VVoVe:
stai confondendo degli errori con dei warning, delle avvertenze

quelli del CSS sono tutti dei warning quindi il CSS può essere considerato validato anche se non li correggi... nel markup invece ci sono degli errori: posta la pagina che li correggiamo
