title: How do I detect the user’s browser and apply a specific CSS file?
body: <p>I need to detect the browser and apply the matched CSS file.</p>
  
  <p>I have created 3 css files: __ie.css, ff.css, opera.css. Now I need to detect the browser in order to include the good one.</p>
  
  <p>I know this </p>
  
  <pre><code>&lt;!--[if IE]&gt;
       &lt;link rel="stylesheet" href="css/ie.css" type="text/css"/&gt;
  &lt;![endif]--&gt;
  </code></pre>
  
  <p>But how do I do the same with Firefox and Opera/Chrome?</p>
