Hi, I am trying to have the thumbnails shaped as a square, instead of landscape-shaped.

If I change the “arve-embed-container” property “padding-bottom: 56.25%”  to 100%, the thumbnail gets to be square, but also affects the position of the video in the lightbox and it gets out of center in the viewing port.

How can I do to limit the scope of the “arve-embed-container” class bottom padding just to the thumbnail? Or is there any other way to change the shape of the thumbnail to a 1:1 proportion?
