I am using the colorbox framework (http://colorpowered.com/colorbox/) and it works great on my site.
However, the CSS does not validate and this is a known issue for this framework:
I wish to exclude colorbox.css from W3C CSS validation. I remember reading about some PHP that will do this, just by enclosing the .css source in a PHP statement, but I can't remember where to find this...
Any help is greatly appreciated.
