title: Using width 1170px with bootstrap.css (responsive)
body: <p>I noticed on the twitter docs for <a href="http://twitter.github.com/bootstrap/scaffolding.html#grid-system" rel="noreferrer">grid system</a> it says the default grid is 940px but it is 1170px on the website. I gather it is using responsive to change the width as I am on a widescreen and higer resolution.</p>
  
  <p>My question falls down to how do I use 1170px like in twitter docs. I can't seem to find any docs explaining how to change the width to 1170px like they have. Is this a custom build they have made but not released or just not updated the docs?</p>
  
  <p>Any ideas how to implement this and have the correct grid customization vars for 1170px.</p>
  
  <p>Thanks</p>
