<cfif Trim(ListGetAt(CGI.HTTP_USER_AGENT, 2, “;”)) EQ “MSIE 6.0″>

<link rel=“stylesheet”
type=“text/css”
href=“css/main_IE6.css”
media=“screen”
/>

<cfelseif Trim(ListGetAT(CGI.HTTP_USER_AGENT, 2, “;”)) EQ “MSIE 7.0″>

<link rel=“stylesheet”
type=“text/css”
href=“css/main_IE7.css”
media=“screen”

<cfelse>
<link rel=“stylesheet”
