title: What does Bootstrap's control-label class do?
body: <p>What CSS formatting is applied to the <code>&lt;label&gt;</code> HTML element by the <code>.control-label</code> Bootstrap 3 class. (<em>I also face difficulties locating that class using Chrome's devtools</em>)</p>
  
  <p>Moreover, in the official Bootstrap 3 <a href="http://getbootstrap.com/css/#forms-horizontal" rel="noreferrer">documentation</a>, <code>.control-label</code> seems to be used only in case of <code>.form-horizontal</code>. Is that true and why?</p>
