@rubengc That didn’t quite work as it still left the top and bottom whitespace on smaller screens. It did point me to the right CSS class though!

Here’s what I did that worked perfectly. Sharing in case anyone else ever needs it.

.gamipress-vimeo-video {
  position: relative; 
  padding-bottom: 56.25%;     
  height: 0; 
  overflow: hidden; 
  max-width: 100%; 
}

.gamipress-vimeo-video iframe {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}
