I searched for a long time on how to hack different browsers in CSS so I thought I’d post techniques for the 3 most popular browsers (IE6, IE7 & Firefox).

The Technique:

I strongly recommend writing CSS and testing it in Firefox. Get it to look right, then hack out IE6 & IE7. Nothing against any of the browsers but this has been the most effective technique for me. You will usually need to make several adjustments to widths and heights, padding and margints, etc in IE6 and IE7 should follow pretty much what Firefox does. There are a few exceptions like floating and positioning that I’ve found.

(more…)

Here’s a quick script that I use in a lot of header files to detect the user’s browser. else represents Firefox in most cases.

<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" type="text/css" href="css/main_FF.css" media="screen" />
    </cfif>
