It’s 2016, and person interface and expertise are extra necessary now than ever. Should you’re constructing a digital id, whether or not or not it's for a web site or utility, “feel and appear” play a particularly necessary half.
With Flash and third-party plugins, like QuickTime, making a fast exit from the browser, and externally-hosted movies and audio tracks being laborious to customize and implement the way in which you’d like, builders eager to implement media could have been left scratching their heads a bit.
Fortunately for us, media is making an enormous push into the limelight as native HTML5. We now have a bunch of various media varieties at our disposal, together with video.
At present, I’m going to indicate you find out how to use native HTML5 video, and implement it within the background of your website. All with out utilizing a plugin. We’ll check out among the native video controls too, to guarantee that a person’s expertise is absolutely enhanced.

HTML5 Video At present
HTML5 video compatibility is de facto excessive. Actually, it’s supported in all trendy browsers (> IE8). The inside workings of video basically may be difficult, particularly while you begin to dig into a number of codecs, tracks, containers, and the works.
I’ll spare you the change for this tutorial, however I recommend taking a learn up on this article I wrote a while in the past. What it's best to know is that while you’re implementing video on the internet, that you must host three codecs:
- MP4 – a container for H.264 video and AAC audio
- Ogg – a container for Theora video and Vorbis audio
- WebM – a container meant primarily to be used within the HTML5
videotag, initially consisting of VP8 video and Vorbis audio, and extra not too long ago VP9 video and Opus audio
To get your video codecs in test, I recommend utilizing the strong ffmpeg tool. Should you simply wish to mess around for now, then mp4 codecs ought to do the trick.
Utilizing video in your HTML5 doc is as simple as this:
If the browser doesn’t assist video in any respect, it’ll simply ignore the supply tags and decide up on the placeholder textual content. Alright, sufficient concept. Let’s dig in.
Setting Up Our HTML
Let’s think about that we wish to construct a web page with a full-screen background video. Let’s say it’s a touchdown web page to your new product, so above that video, we would like some heading textual content, some sub-text, and a name to motion button. Fairly simple stuff proper? Nicely, virtually.
We are able to’t fairly have only one container with a background video in CSS, and the textual content inside that container. CSS doesn’t enable for video.
What we are able to do although is a few primary CSS trickery that’ll enable us to place our video completely in our mother or father container, breaking the common movement of the doc. Let’s check out what the markup may appear to be:
Now if we wrap this in an HTML5 doctype and cargo it up in a browser window, we’re going to see one thing fairly ugly trying. Don’t fear, we’re going to repair that. Let’s dig into some CSS.
Laying The CSS Base
As a result of we’re solely utilizing a number of parts on this demo, I gained’t use any CSS reset or normaliser. Let’s simply write up our personal:
html, physique, div, h1, p, a, video
On prime of that, let’s eliminate the default font, and embody Oxygen from google fonts.
Be sure to incorporate the viewport declaration for responsive internet design too. Our full HTML doc ought to now appear to be this:
Background Video
Bear in mind, we’re keen on a full display screen video and viewport, so we'd like to ensure our html and physique parts are full display screen. Our base CSS ought to now appear to be this:
/* ============================================================================= RESETS ============================================================================= */ html, physique, div, h1, p, a, video /* ============================================================================= HTML, BODY ============================================================================= */ html, physique physique
Alright, let’s transfer on!
Layering Our Content material
We all know we would like our content material layered, and meaning we have to leverage z-indexing. Our content material itself will exist within the regular movement of the HTML, however our video will stay mounted and within the background. Let’s begin with that:
/* ============================================================================= CONTENT ============================================================================= */ .content material /* ============================================================================= VIDEO ============================================================================= */ .video
Let’s add a little bit extra type to our content material in order that we are able to neglect about it and give attention to our video. We’ll make that heading huge and daring, and elegance the button a little bit bit too. I’ll simply use some eyeball averages to get the content material vertically centred, however there are different tips (as we’ll see later). Right here’s what I got here up with:
.content material .content__heading .content__teaser .content__cta
Fairly simple stuff, however at the least now there’s some visible enchantment, which makes it a bit simpler for us to work. Now, we've a little bit of a difficulty with our video. Proper now, it’s simply pinned to the top-left of the display screen, and for those who’re on an even bigger display screen, it’s possible not occupying all out there house. Let’s take a look at that.
Centring & Full-Screening The Video
There’s a nifty little trick floating round as of late for sustaining an ideal vertical centre of a fully (or mounted) positioned factor relative to its container. It leverages prime and remodel. The interpretation of a component by a share worth is calculated based mostly on the weather dimensions.
So if we nudge one thing 50% from the highest of a container, then translate it again up a unfavourable 50%, will probably be completely centred. That leaves us with this:
.video
Now, what about full-screening it? Nicely, we've to drive that with a little bit little bit of CSS once more, utilizing minimal widths and heights. Right here’s the total CSS for the video:
.video
Now, we've a full display screen video within the background! However wait a second…it’s not even taking part in. Let’s deal with that now.
Controlling The Video
There are a bunch of attributes at our disposal, and you'll view all of them here. We’re solely keen on three of them, however take observe that by default, the controls are hidden from view. As a result of we’re attempting to realize one thing that’s purely aesthetically pleasing, we are going to preserve it this manner. The opposite three attributes we’re keen on are:
autoplay– if specified, the video will mechanically start to playmuted– signifies the default setting of the audio contained within the videoloop– if specified, we are going to, upon reaching the tip of the video, mechanically search again to the beginning
Autoplay is necessary, as a result of we’re hiding the controls within the first place, and we would like the video to really play. Muted can be necessary, and right here’s why. It’s already a little bit bit intrusive to outplay a video and never enable a person to pause or cease it. However we are able to excuse ourselves a bit, as a result of it’s all within the title of aesthetic worth.
Nonetheless, if we're auto-playing a video, we undoubtedly wish to mute it by default. Lastly, there’s the loop attribute. This isn’t actually necessary so to talk, however simply know that when you have a looping video clip, then this attribute takes care of that simply. Let’s add these three attributes to our video:
Hit refresh within the browser, and voila! You’re all achieved, and it appears lovely.

Issues & Taking It Additional
We’re not contemplating one thing that I believe is a bit necessary although, and that’s the truth that not everybody viewing your website is viewing it from a high-speed connection. Auto-playing an HD video on a slower connection can lead to a jerky, disagreeable expertise. Fortunately for us, the video will by default present the primary body, giving customers the looks that it’s only a background picture. With that in thoughts, we are able to current the video to the person with autoplay off, and play the video solely when it’s prepared. How will we do this although?
HTML5 video is underneath the “media” umbrella, and as such, there are numerous methods to work together with it, fetch information, and fireplace occasions. If we take a look at among the methods out there to us, we’ll decide up on the truth that we are able to really play the video through the JavaScript methodology play(). Additionally, if we check out among the media events out there to us, we’ll see two occasions of explicit curiosity:
canplay– despatched when sufficient information is accessible that the media may be performed, at the least for a few framescanplaythrough– despatched when the prepared state adjustments … indicating that all the media may be performed with out interruption
You’ll need to resolve which one you’re going to make use of, however for now, let’s simply stick to canplay. First, we’ll take away autoplay from our video:
Now, let’s work together with it utilizing some quite simple, however neat JavaScript:
(perform() )();
Fairly nifty, huh?
Caveats
Now, it’s crucial to notice that media occasions and strategies are very trendy stuff, and browser assist is scattered in every single place. However be aware of all of this although, as a result of it’s right here to remain, and can solely turn out to be extra supported sooner or later.
For now although, be sure to have the mandatory checks arrange for varied browsers, when to make use of what, and if to incorporate the JS snippet above in any respect. Ah, the fashionable internet.
With just a bit little bit of understanding, CSS trickery, and experimentation, we have been in a position to create a visually gorgeous impact.
