title: How to center the ".input-group-btn" in bootstrap?
body: <p>How to center the bootstrap <code>input-grop</code>?</p>
  
  <p>Here is the <code>jsfiddle</code>: <a href="http://jsfiddle.net/Qs4T9/" rel="nofollow noreferrer">http://jsfiddle.net/Qs4T9/</a></p>
  
  <p>I would like to make the <code>input-grpup</code> in the center of the row, but without manually calculating all that offsets. Would be better if it would be something like <code>.text-center</code>, <code>display: table</code>, <code>display: table-cell</code> or similar.</p>
  
  <p>Here is an "answer" [ <a href="https://stackoverflow.com/questions/18036315/centering-bootstrap-input-fields">Centering Bootstrap input fields</a> ], but it's not a really centering, looks more like just a workaround for the concrete elements and the sizes, not a general solution (at least for the whole non-mobile scheme).</p>
