Goodbye Forever, .css Files

Designers: when was the last time you created a new file with an .html extension? Hopefully, it’s been quite a while. I personally have the habit of making even the most mundane Under Construction Splash a PHP file, just in case I want the file to be able to do something.

CSS files are just text files with a fancy extension. Lose ‘em. Their utterly static nature is a harbinger of inflexibility that will result in silly find/replace changes down the line. I urge you to abandon the arbitrary .css extension altogether, and instead create your CSS files in PHP.
