ho preso da http://www.dynamicdrive.com/dynamicindex2/crosstick.htm questo js che mostra le news con uno scroller verticale.
e dato che non era corretto secondo il validator del w3c (validator.w3.org), l'ho riadattato
ora funge che è un piacere
sto cercandone adesso uno orizzontale, nel mentre vi posto il codice di questo qua, basta inserirlo nel body del corpo.
codice:
<div style=" margin: auto auto; width: 620px; background-color:#FF9900; text-align:center; " >
<script type="text/javascript" >
