Make video fit 100% with any screen resolution - css

Question

I have a video with the following properties, Frame width: 1920 and Frame Height: 1080. I need its width and height to be 100% thus filling up the whole screen. And it needs to be responsive too. So far, I have this code :
<video class="hidden-xs hidden-sm hidden-md hidden-custom videosize embed-responsive-item" autoplay="autoplay" loop="loop">
<source src="~/Videos/myvideo.mp4" type="video/mp4" />
</video>
css:
.videosize {
position:absolute;
z-index:-1;
top:0;
left:0;
width:100%;
height:100vh;
}
With the code above it fits perfectly with a 1680 x 1050 screen resolution, however with other resolution, it takes up 100% of the height then the width adjusts leaving white spaces on both sides.
Any idea ? Thanks.

Found a good solution here: http://codepen.io/shshaw/pen/OVGWLG
So your CSS would be:
.video-container {
position: absolute;
top: 0;
bottom: 0;
width: 100%;
height: 100%;
overflow: hidden;
}
.video-container video {
/* Make video to at least 100% wide and tall */
min-width: 100%;
min-height: 100%;
/* Setting width & height to auto prevents the browser from stretching or squishing the video */
width: auto;
height: auto;
/* Center the video */
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}
HTML:
<div class="video-container">
<video>
<source src="~/Videos/myvideo.mp4" type="video/mp4" />
</video>
</div>

You can now use the object-fit property. This property has been designed especially to manage responsive size for <img> and <video> elements. It is now supported by all modern browsers.
.videosize {
position: absolute;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 100%;
object-fit: cover;
}

.video-container {
position: absolute;
top: 0;
bottom: 0;
width: 100%;
height: 100%;
overflow: hidden;
object-fit: fill;
}
.video-container video {
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
This worked for me.

Answer 4

I Set the height of the video Tag and it solved the problem:
<video height="600" autoplay="true" loop="true" muted="true" plays-inline="" style="position: absolute; right: 0; top: 0; min-width:100%; z-index: -100; object-fit: cover;">
<source src="assets/vid/grapes.mp4" type="video/mp4"> </video>

Answer 5

This worked amazingly: https://css-tricks.com/fluid-width-video/
video {
/* override other styles to make responsive */
width: 100% !important;
height: auto !important;
}

Answer 6

Can you use an iframe?
/* Flexible iFrame */
.flexible-container {
position: relative;
padding-bottom: 56.25%;
padding-top: 30px;
height: 0;
overflow: hidden;
}
.flexible-container iframe,
.flexible-container object,
.flexible-container embed {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
<!-- Responsive iFrame -->
<div class="flexible-container">
<iframe src="URL" frameborder="0" style="border:0"></iframe>
</div>

Answer 7

Using object-fit: cover; was my solution.
As of 2021 it is supported by all major browsers.
object-fit support
CSS Example:
.video-wrapper {
overflow: hidden;
display: flex;
align-items: center;
justify-content: center;
}
.video-wrapper video {
object-fit: cover;
}

I know it's an old post but I guess this can help?
*{
margin: 0 !important;
}
html{
height: 100vh;
}
body{
height: 100%;
overflow: hidden;
}
.wrapper{
width: 100%;
height: 100%;
}
.wrapper video{
height: 100%;
width: 100%;
background-color: red; /* I added bg color here so you can see how the video cover the page */
}
<div class="wrapper">
<video>
<source src="video.mp4" type="video/mp4">
</video>
</div>
