Html5 video background, keep center of video in center

Question

I am trying to keep a background video centered regardless of how big the user drags the video. It\'s currently cutting off the right side of the videos when i scroll smalle

Answer 1

In my use case where I always wanted the video to cover the entire viewport (no matter if the viewport aspect ratio was bigger or lower than the videos), the above solution didn't work exactly how i intended. Instead, the following worked much better:

.video-container {
  position: absolute;
  top: 0;
  left: 0;
  width: 100vw;
  height: 100vh;
}
.video-container > video {
  display: block;
  position: absolute;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
  z-index: 1;
}
@media screen and (max-aspect-ratio: 1920/1080) {
  .video-container > video {
    height: 100%;
  }
}
@media screen and (min-aspect-ratio: 1920/1080) {
  .video-container > video {
    width: 100%;
  }
}

My video was 1920x1080, and this works in IE11 (didnt test lower) and beyond.
