title: Put some text next to Bootstrap 3 input
body: <p>I have got the Bootstrap 3 code below:</p>
  
  <pre><code>&lt;div class="form-group"&gt;
      &lt;div class="col-sm-3 control-label"&gt;
          &lt;label&gt;Surname:&lt;/label&gt;
      &lt;/div&gt;
  &lt;div class="col-sm-9"&gt;
      &lt;input class="form-control" type="text" name="surname"&gt;&lt;span&gt;!&lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And I need to show the exclamation mark next to the input, but it is always on the new line. How to put it nex to the input, please?</p>
  
  <p>Thanks</p>
