>can i have an example for the same

The following applies a stylesheet for IE or for any other browser:

if (document.all)
{
   document.write("<link rel='stylesheet' href='/Stylesheet.css' type='text/css'>")
}
else
{
   document.write("<link rel='stylesheet' href='/Netscape.css' type='text/css'>")
}

Of course, you have to build your own stylesheets, adjust the path here and add a line like this at the top of your page:

<script language=JavaScript src=Javascript/Stylesheet.js></script>
