Question:

We install the video gallery, but its not responsive, and the thumbwidth and thumbheight attribute doent work to set the dimensions of the thumbnails.

Theres the code :

<div class="html5gallery" data-width="1000" data-height="560" thumbwidth="140" thumbheight="85" data-showimagetoolbox="always"  data-skin="light" style="display:none;">

Answer:

You need to add data-responsive="true" to your div. For more details, you can check http://html5box.com/html5gallery/install.php#skinandsize

For the thumbnails, it's because you did not add "data-" prefix to the parameters. You can change your code to the following:

<div class="html5gallery" data-responsive="true" data-width="1000" data-height="560" data-thumbwidth="140" data-thumbheight="85" data-showimagetoolbox="always"  data-skin="light" style="display:none;">
