Fix a malformed page deck

If you edit a source file by hand, you may see the following error message may occur when you try to open the file in Google Web Designer:

This file contains a malformed page deck. If the file was edited by hand, please make sure there is exactly one page deck containing only pages as children, and make sure each page has a single child with the class gwd-page-content

You can fix the file by editing the source HTML to move elements that are outside the gwd-page-content class.

Example of a malformed page deck in a banner ad:

<div is="gwd-pagedeck" class="gwd-page-container" id="pagedeck">
    <div is="gwd-page" id="page1" class="gwd-page-wrapper gwd-page-size gwd-lightbox" data-gwd-width="300px" data-gwd-height="250px">
      <div class="gwd-page-content gwd-page-size"></div>
      <div>element</div>
    </div>
  </div>

The highlighted element in the code above is the problem, as it's outside the div with the gwd-page-content class. Move this element inside the gwd-page-content div.

Example of the fixed source code:

<div is="gwd-pagedeck" class="gwd-page-container" id="pagedeck">
  <div is="gwd-page" id="page1" class="gwd-page-wrapper gwd-page-size gwd-lightbox" data-gwd-width="300px" data-gwd-height="250px">
    <div class="gwd-page-content gwd-page-size"><div>element</div></div>
  </div>
</div>
