title: How do I ensure my twitter bootstrap theme fits for all devices?
body: <p>I am designing new website <a href="http://jobpixels.com" rel="nofollow">Jopixels</a> to provide free themes for Twitter Bootstrap.
  Bootsrap provides support for responsive deign. But in my themes I need to write my theme specific CSS that I need to ensure that it fits for all kind of devices.</p>
  
  <p>I can not buy a Tablet or Smartphone to check test my design.</p>
  
  <p>What is the correct way to ensure my designs are cross device compatible without real devices?</p>
