hi!
I would like well that for each navigator that I can use a different CSS but my code does not function under eZ.
But the same code functions well apart from eZ.
Here my code javasript:

<script language="JavaScript" type="text/javascript">
var nn = (document.layers) ? true : false;
var ie = (document.all) ? true : false;
var dom = (document.getElementById && !document.all) ? true : false;
var oper= (document.all && (navigator.userAgent.toLowerCase().indexOf("opera") != -1)) ? true : false;
if (oper){
document.write( '@import url({"stylesheets/opera.css"|ezdesign(no)});');
}
else if (ie) {
document.writeln(''@import url({"stylesheets/ie.css"|ezdesign(no)});');
}
else if (dom || nn) {
document.write( '@import url({"stylesheets/nce.css"|ezdesign(no)});');
}
</script>

You need to escape the bractes ( { & } ) used in you javascript code.
Take a look in the doc, search/look for the 'ldelim', 'rdelim' and 'literal' template functions.

thank you for your answer but the problem always continues! I still do not manage to apply the CSS for each navigator here my modified code:
{literal}
<script language="JavaScript" type="text/javascript">
var nn = (document.layers) ? true : false;
var ie = (document.all) ? true : false;
var dom = (document.getElementById && !document.all) ? true : false;
var oper= (document.all && (navigator.userAgent.toLowerCase().indexOf("opera") != -1)) ? true : false;
if (oper){
document.write( '@import url({ldelim}"stylesheets/opera.css"|ezdesign{rdelim});');
}
else if (ie) {
document.writeln('@import url({ldelim}"stylesheets/ie.css"|ezdesign{rdelim});');
}
else if (dom || nn) {
document.write( '@import url({ldelim}"stylesheets/nce.css"|ezdesign{rdelim});');
}
</script>
{/literal}

Do not use {ldelim} together with {literal}. If you are using {literal} then replace {ldelim} with { and same for {rdelim}, repalce with }.

BTW, Opera, Gecko and Webkit based web browsers support web standards better then IE. In most cases the IE conditional comments are sufficient to fix issues. Do you really need this check?

hi!

I need really this control for the need for my site! For what of IE, I think find a means of resoudre the problem. But the difficulty remains on other navigators. Isn't it possible to make this control with eZ?

Here is how you could do it:

<script language="JavaScript" type="text/javascript">
<!--
if ( window.opera )
    document.write( '<link rel="stylesheet" type="text/css" href={"stylesheets/opera.css"|ezdesign} \/>');
else if ( document.all )
    document.writeln('<link rel="stylesheet" type="text/css" href={"stylesheets/ie.css"|ezdesign} \/>');
else if ( document.getElementById || document.layers )
    document.write( '<link rel="stylesheet" type="text/css" href={"stylesheets/nce.css"|ezdesign} \/>');
//-->
</script>

And here is how you use javascript brackets inside templates:

<script language="JavaScript" type="text/javascript">
<!--
if ( window.opera )
{ldelim}
    document.write( '<link rel="stylesheet" type="text/css" href={"stylesheets/opera.css"|ezdesign} \/>');
{rdelim}
else if ( document.all )
{ldelim}
    document.writeln('<link rel="stylesheet" type="text/css" href={"stylesheets/ie.css"|ezdesign} \/>');
{rdelim}
else if ( document.getElementById || document.layers )
{ldelim}
    document.write( '<link rel="stylesheet" type="text/css" href={"stylesheets/nce.css"|ezdesign} \/>');
{rdelim}
//-->
</script>

But this way of browser sniffing is not very modern, this is how web developer did things 5-10 years ago.
Today most web developers tend to code for new browsers, and have extra css that is added for older browsers, witch is mostly internet explorer..

<!-- first include you standard css, then for ie 6 and lower, then ie 7 -->
<!--[if lt IE 7]>
<link rel="stylesheet" type="text/css" href={"stylesheets/ie6.css"|ezdesign} />
<![endif]-->
<!--[if IE 7]>
<link rel="stylesheet" type="text/css" href={"stylesheets/ie7.css"|ezdesign} />
<![endif]-->
