   <h2 id="forms-control-validation">Validation states</h2>
   <p>Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add <code>.has-warning</code>, <code>.has-error</code>, or <code>.has-success</code> to the parent element. Any <code>.control-label</code>, <code>.form-control</code>, and <code>.help-block</code> within that element will receive the validation styles.</p>
