Why simply use PHP variables for dynamic stylesheets? <p>I've been reading about dynamic stylesheets and have stumbled across several options, including sass, and less. But my question is why not just turn my <code>stylesheet.css</code> into <code>stylesheet.css.php</code> and simply use php variables. Then, I avoid all the dependency issues associated with all these other approaches. </p> <p>Am I overlooking some serious problems by doing it this way?</p>
