title: How to have a centered bootstrap layout
body: <p>I need to create a responsive layout, and I have used bootstrap before but I have never actually attempted this. Making full width designs is plenty easy, but I want a two column layout that would say.. have a max width of 900px together.</p>
  
  <p>The example of what I am trying to do can actually be seen right here on stackoverflow. There are two columns to this site, but both columns are centered on the page right now with space to the left and right. I just need that (and responsive as well for smaller screens).</p>
