title: CSS on Server Side?
body: <p>I ran into <a href="http://lesscss.org/">LESS website</a> and this is the description of they are doing"</p>
  
  <blockquote>
    <p>LESS extends CSS with dynamic behavior such as variables, mixins, operations and functions. LESS runs on both the client-side (IE 6+, Webkit, Firefox) and server-side, with Node.js. </p>

  <p>What does it mean "and server-side" with Node.js? I know that you can write server-side code with javascript using Node.js, but what is the meaning of having CSS on server-side and how is it useful?</p>
