title: Grid systems on retina display
body: <p>I hope this isn't an awful question, but how do grid systems like 960 or bootstrap play with retina displays? </p>
  
  <ol>
  <li>If I design for 1170px on a non-retina display but it's viewed on a retina display, will my site and images look blurry on retina? </li>
  <li>Do I just have to worry about images or is there anything else I have to worry about when designing?</li>
  </ol>
  
  <p>Am I missing something here? :O</p>
