Responsive Video Background

Using a fullscreen HTML5 responsive video background has become very popular in web design lately. We know that fullscreen images used as backgrounds have an incredible visual impact, but did you know that you can use video in the same way by using HTML5 tags and bit of CSS.

Good video in the background can quickly make people stop and examine it, increasing the time they spend on the site.

This extended time on the site could potentially lead to more interaction with the other content on the page.

Even as we can’t yet set a video for the background or background-image CSS properties. They could be most effective take bitmaps, SVG photographs, shades and gradients as values.

It’s far possible to fake the appearance of HTML5 Responsive Video background by forcing it at the back of other HTML factors. The assignment is to have the video fill the browser window, making it as responsive as background images.

The video will possibly set to autoplay, but it has to mute through default; preferably, it should now not consist of sound at all. (you could without problems create an unmute button for the video with JavaScript).

The video should display a placeholder photo, falling back to a static background picture for browsers that don’t help HTML5 or don’t support HTML5 element tag. The placeholder image can also use a background on mobile devices. Remember that, most phones and tablets do not support autoplay, for obvious reasons.

Fullscreen HTML5 Responsive Video Background Implementation

Let’s start how the HTML will be written. We need to create a simple HMTL5 video element with the loop, autoplay, and muted attributes.

The poster picture will be replaced by the first frame of the video when it loads, so it makes feel to derive that photograph from the same first frame.

Please note that the order of the video files is critical. Currently, Chrome didn’t support autoplay a Webm video if it comes after something else.

Now we can get onto a few coding! The new HTML5 video tag makes it exceptional and smooth to embed videos in your website. Note that we’ve got a line for every of our video shorts, and a few text if the browser doesn’t always support the video.

Here is background video HTML code example.

<video autoplay  poster="images/poster.jpg" id="video by" loop>
<source src="images/video.webm" type="video/webm">
<source src="images/video.mp4" type="video/mp4">
Your browser does not support the video tag. I suggest you upgrade your browser.

Fullscreen HTML5 Responsive Video Background Styling

To achieve a video that fills the screen for both width and height, we need to set the position fixed with top and left should be 50%.

In addition, you could also add a ‘min-height:100%’ to ensure that you don’t get any vertical scroll bars. With this method, the min-width or height will always be used without any scrolling.

video#videobg { 
position: fixed;
top: 50%;
left: 50%;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -100;
transform: translateX(-50%) translateY(-50%);
background: url('images/poster.jpg') no-repeat;
background-size: cover;
transition: 1s opacity;

Older browsers will no longer understand the video formats, but should still recognize the basic video tag (except IE8).

For the one’s browsers, we create a background-image for the element, using the same placeholder picture. At this degree most effective Safari (mobile and desktop) requires the -webkit vendor prefix for transforms, so it has been included in the code;

if you’re also targeting Firefox 15 or earlier, you’ll want to include a -moz prefixed version of the transform.

You need to have now a video that fills all the available space on the display screen. As an evidence of how this works; we’re telling the video to use the most available width or height, but as it will hold its aspect ratio this may suggest it will overflow over the full-screen size (unless you happen to be browsing in the perfect screen size).
