title: Force desktop browser to open mobile site
body: <p>I created a web site for my school in 2 versions, one for pc and one for mobile.
  I use the following code to check if the device is mobile:</p>
  
  <pre><code>if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
   // mobile...
  }
  </code></pre>
  
  <p>I want to force some users to direct the mobile site, without changing the code above... can i give to the browser document some property and then the browser will think its mobile?</p>
