Enable Page Interaction in Preview Mode

How to allow page interaction in Blogger post preview mode.

When you enter post preview mode, there's this top layer element that prevents page interaction (clicking, dragging, etc.).

To disable it, add the following CSS:

.blogger-clickTrap{display:none}

or if you prefer a template code:

<b:if cond='data:view.isPreview'>
  <style>
    .blogger-clickTrap{display:none}
  </style>
</b:if>
