Salve a tutti ....come da titolo vorrei poter utilizare questo news-ticker ma ho alcune lacune in js e non so come poterlo far funzionare con un doctype diverso.....

mi spiego meglio...

ho questo script che funziona egregiamente sia su windows (e te pareva che non funzionava!!) ed anche su Firefox (che è quello che mi interessa di più) ma se vado a cambiare il doctype della pagina allora tutto va a farsi friggere!!

Per windows funziona sempre ma non rimane più ristretto dentro al div e quindi il testo scorre su tutta la sua larghezza uscendo quindi dal div.

Su firefox invece oltre a vedersi il testo su tutta la larghezza del monitor, il testo rimane fermo!!!

Vi posto ora lo script con il doc-type funzionante:

codice:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
	<title>Untitled</title>

<script type="text/javascript" language="JavaScript">

a questo punto se cambio il doctype esistente con questo :

codice:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
allora non funziona più nulla!!!

Scusate la lunghezza del post e spero che qualcuno di voi mi possa dare una mano d'aiuto a risolvere!!

Grazie mille in anticipo...
