title: Set border color on summernote focus state
body: <p>I would like to set the border color of the summernote div to a light blue color on focus and set it back to neutral on focusout. </p>
  
  <p>I managed to remove the shadow around the div by using the following:</p>
  
  <pre><code>div.note-editor.panel.panel-default {
      box-shadow: none;
  }
  </code></pre>
  
  <p>The problem I have is I haven't found the way to style its state when focused. Using .focused or :focus did not help either.</p>
