title: Twitter bootstrap: Is it possible to center container-fluid with two rows with span5 or span4?
body: <p>I have something like this <img src="https://i.stack.imgur.com/LTe2j.png" alt="enter image description here"></p>
  
  <p>I have these in a row-fluid with span6. However, I when I do span5 on both of them, they float off the left side, leaving a lot of white space on right free. Can I center them on page ?</p>
