title: Is it possible to pass parameters to css file?
body: <p>I see a statement like the following in HTML source</p>
  
  <pre><code>&lt;link rel='stylesheet' type='text/css' href='/css/jquery-ui.css?700241AD2550.node' /&gt;
  </code></pre>
  
  <p>What does this mean? Is it like passing a param or a suffix to the filename?</p>
