  Draggable regions can be defined using the -webkit-app-region CSS property.
  <br/>In the below example the red region is draggable and the blue sub-region is non-draggable.
  <br/>Windows can be resized by default and closed using JavaScript <a href="#" onClick="window.close(); return false;">window.close()</a>.
  <div class="draggable">
    <div class="nondraggable"></div>
