It’s probably quite a well documented subject already, but just thought I would shed some light on producing dynamic CSS using ColdFusion. Instead of linking to a static stylesheet in your webiste, you can link to a .cfm template and get ColdFusion to produce the CSS code for you, allowing you to switch graphics, colours, fonts etc. all when the stylesheet is loaded in. As an example …

<link rel=”stylesheet” type=”text/css” href=”http://yourdomain.com/css/stylesheet.cfm” / >

Inside the file stylesheet.cfm you would have something similar to below …

<cfoutput>
<cfheader name=”content-type” value=”text/css” />
<cfset fontSize = 11 />
body {font-size:#fontSize#px;}
…….. etc.
</cfoutput>

That’s all there is to it. Very simple but very effective and allows you to use a database, xml files or standard text files to switch your application look and feel dynamically.
One really important line in the code above is the <cfheader> tag. Without this line, Mozilla based browsers, will not render the CSS correctly. IE will render, in it’s lovely quirks mode!
