Html5 video background, keep center of video in center
This is much shorter and worked for me.
video {
position: fixed;
right: 0;
bottom: 0;
min-width: 100%;
min-height: 100%;
transform: translateX(calc((100% - 100vw) / 2));
}
here's how I typically do background video, and how I did it for the stre.am landing page:
.video_contain {
position: absolute;
top: -50%;
left: -50%;
width: 200%;
height: 200%;
}
video {
position: absolute;
top: 0;
bottom: 0;
right: 0;
left: 0;
margin: auto;
min-height: 50%;
min-width: 50%;
}
.bg-video-wrap {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
.bg-video-wrap > video,
.bg-video-wrap > iframe {
object-fit: cover;
object-position: center center;
width: 100%;
height: 100%;
}
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.
