here is the actual code that i use. .

<?php $browser = $_SERVER['HTTP_USER_AGENT']; ?>
<?php if (strstr($browser, "MSIE 6.0")) { ?>
<link rel="stylesheet" href="ie6style.css" type="text/css" media="screen" />
<?php }else{ ?>
<link rel="stylesheet" href="default.css" type="text/css" media="screen" />
<?php } ?>

$_SERVER['HTP_USER_AGENT'] will return the users browser information, which i inserted in the variable $browser, then i use the string function strstr which is String Find. for IE6 use “MSIE 6.0″, IE7 “MSIE 7.0″ for all versions of Internet Explorer just use “MSIE”.

to separate styles of other browser you may use the following in the string find function. .

IE – “MSIE”

Firefox – “Firefox”

Safari – “Safari”

Opera – “Opera”

Chrome – “Chrome”

for specific browser version just type space after the browser name then type the version number.

if you are separating style only for Internet Explorer you may also use Conditional Statement

this does not require PHP or Javacript.

the code is.

<!--[if IE]>
// put your ie stylesheet here
<![endif]-->
<!--[if !IE]-->
// put your default stylesheet here
<![endif]-->
