Salve a tutti ragazzi sono nuovo di questo forum.

Vi scrivo perchè avrei bisogno di un aiuto: sto modificando un template di joomla ma ho diversi problemi.
Quello principale è che inserendo un menu a comparsa,non mi da lo stesso risultato fra ie e firefox,come posso procedere?
Il menu che compare me lo ritrovo in diverse posizioni a seconda che usi firefox o ie

Questa è la prima parte del mio file css

codice:
body, html { margin: 0;padding: 0;font: 14px/140% "Trebuchet MS", Tahoma, Verdana, Helvetica;color: #666;background-color: #3366FF; } 
/*body { background: #FFF url(../images/body_bg.png) repeat-x center bottom;margin: 0;padding:0; }*/  

/* Basic link styles */  
a:link, a:visited { color: #2685c7; }  
/* @end Basic link styles */  


/* @group top menu bar */
