title: Must Bootstrap container elements include row elements?
body: <p>From my reading of the documentation, it seems that <code>.container</code> is the "parent" wrapper for the <code>.row</code> and the divs that contain the <code>.spanX</code> (where the x totals 12). However, it doesn't seem like there is a <code>.row</code> in their navigation example.</p>
  
  <p>Also, on their documentation site, the <code>.container</code> is wrapped by a couple of navbar related divs.</p>
  
  <p>Can anyone elaborate a bit on how the framework should work? I'm new to it.</p>
