Ora funzionano ne più ne memeno come prima..provo a spiegartelo.
Questo è il codice HTML contenente tutti e due le gallery.



codice:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Documento senza titolo</title>
<link href="PORTFOLIO2.CSS" rel="stylesheet" type="text/css" />
<link href="easyslider1.7/css/screen.css" rel="stylesheet" type="text/css" media="screen" />
<link href="easyslider1.7/css/screen2.css" rel="stylesheet" type="text/css" media="screen" />

<script  src="03/jquery.js" type="text/javascript"></script>

<script src="03/main.js" type="text/javascript"></script>


	<meta http-equiv="content-type" content="text/html;charset=UTF-8" />    

	<script type="text/javascript" src="easyslider1.7/js/easySlider1.7.js"></script>
	<script type="text/javascript">
		$(document).ready(function(){	
			$("#slider").easySlider({
				auto: false, 
				continuous: true
			});
			$("#slider_gallery").easySlider({
				auto: true,
				continuous: true 
			});
		});	
	</script>





</head>

<body>
<div id="header"></div>



<div id="content">
		<div id="slider">

		</div>
</div>


</div>
 
 
 <div id="container">

  <div id="content_gallery">

			[/list]
		</div>
</div>
  



  

  </div>
  
  <div id="footer"></div>
</body>
</html>


A questo codice ho provato a colegare due differenti pagine CSS (screen.css e screen2.css)
Il risultato è pressochè identico.
Se non si và a premere il bottone next sulla gallery che sta immobile sembra funzionare tutto ma se si preme il next o il prev questo sposta tutte e due le gallery.


Questi due codici .CSS

Avevo pensato che fosse un buona idea creare pagine .js a parte per ogni script a cui collegare poi i relativi .css ma leconoscenze che ho non riescono a farmelo mettere in pratica....non so poi quanto buona possa essere l'idea
