Grazie.
Tra i

va bene ! Lo script che mi segnali ,lo ho tolto.La pagina e' stata validata ! (sia Css che Html ).
( solo localmente perche' online ci sono le tabelle di pubblicita' di yahoo che rompono..).
I pulsanti rimangono il doppio di quelli del sito originale !(e della
pagina relativa che ho scaricato ) >>>
http://www.cssplay.co.uk/menus/drop_definition.html

Questo dopo che vi ho inserito il codice del layout liquido preso
da un articolo in Css.Html.it che ora non riesco piu' a trovare e lo
attacco sotto .
L 'errore sparisce se cancello il file di text/css .
Quale parametro sara ?

(E' un DOCTYPE HTML, che inserisco in un XHTML....alla fine comunque validato) >>>>
