One of those troubles is the class attribute of a generic HTML; I found that in IE you cannot simply set a class attribute to your own HTML node, but you have to set a className node with the list of your CSS classes.
This is THE code:
/* find out which is the browser */
var isIE = (window.ActiveXObject)?true:false;
var isMozilla = (document.implementation.createDocument)?true:false;
/* the name of the attribute, depending on the browser */
var attributeClass = (isIE)?"className":"class";
/* set the attribute */
Moreover there is also another strange behavious as for the style attribute; if you want to set the whole CSS text of a node's style (and not a particular sub attribute), this is the syntax:

Max and other users made me notice that "else if(isMozilla)" may exclude other
kind of browser, not allowing a wide "cross browsering". Thanx guys!
var styleString ="font-size:10px;";
I assure you: writing cross browser script is a really butchery task! Try if you don't believe me!
