Hope you have got a some idea about the video tag in HTML5. So we will proceed to add a video tag HTML.

HTML Video Tag

<video autoplay controls>
 <source src="video.mp4" type="video/mp4">
 <source src="video.ogg" type="video/ogg">
 <source src="video.webm" type="video/wemm">
 Your browser does not support the video tag.
</video> 

Inside the video tag, we need to add the different supported video formats using the source tag. Mention the video type also. A line which says ‘Your browser does not support the video tag’ to be included in the video tag. If the browser does not support the video tag, the message will be displayed. We have added the attributes height, width. The ‘control’ attribute will enable the video controls. When we use video as a background, we can avoid ‘controls’. Also, add loop, if you want the video to be repeated.

CSS to fix the Responsive background video

Here we will use few lines of css to fix the video as a background. Following is the css.

video {
    position: fixed;
    min-width: 100%;
    min-height: 100%;
    width: auto;
    height: auto;
    z-index: -1;
}

Make the video as position fixed/absolute, and using z-index, position it behind the main content. Add min-width and min-height. And width and height as auto. So that when displayed in different resolutions, it will occupy the full window.
