title: using php to serve CSS files
body: <p>Is this a good idea to serve a css file by php ?</p>
  
  <p>Actually I have a large CSS file which include all media query so I thought to serve only selected section based on the argument passed to the php page 
  Eg In my original php page I will do like this </p>
  
  <pre><code>&lt;link rel="stylesheet" type="text/css" href="css.php?&lt;?= "theam=".$theam ."&amp;screen=".$screen ?&gt;"/&gt;
  </code></pre>
  
  <p>and in the css.php file I will check the condition to give response with only required css is this the correct Way ? </p>
