Html – Responsive fullscreen youtube video with no black bars

csshtmlvideoyoutube

I have a fullscreen youtube video embedded on my website.

enter image description here

It looks good when the size of the browser is proportional to the video’s width and height. However, when I resize the browser to a different proportion, I get black bars around the video.

enter image description here

What I want is to have the video fill the whole window at all times, but without any stretching. I want the “excess” to hide when the browser size is not proportional to the video.

What I am trying to achieve is something you can see in the background of these two websites: http://ginlane.com/ and http://www.variousways.com/.

Is it possible to do this with a youtube video?

This is pretty old but people may still need help here. I needed this too so have created a Pen of my solution which should help - http://codepen.io/MikeMooreDev/pen/QEEPMv

The example shows two versions of the same video, one as standard and the second cropped and centrally aligned to fit the size of the full parent element without showing the hideous black bars.

You need to use some javascript to calculate a new width for the video but it's really easy if you know the aspect ratio.

HTML

<div id="videoWithNoJs" class="videoWrapper">
  <iframe src="https://www.youtube.com/embed/ja8pA2B0RR4" frameborder="0" allowfullscreen></iframe>
</div>

CSS - The height and width o the videoWrapper can be anything, they can be percentages if you so wish

.videoWrapper {
  height:600px;
  width:600px;
  position:relative;
  overflow:hidden;
}

.videoWrapper iframe {
    height:100%;
    width:100%;
    position:absolute;
    top:0;
    bottom:0;
}

jQuery

$(document).ready(function(){
    // - 1.78 is the aspect ratio of the video
    // - This will work if your video is 1920 x 1080
    // - To find this value divide the video's native width by the height eg 1920/1080 = 1.78
    var aspectRatio = 1.78;

    var video = $('#videoWithJs iframe');
    var videoHeight = video.outerHeight();
    var newWidth = videoHeight*aspectRatio;
    var halfNewWidth = newWidth/2;

    video.css({"width":newWidth+"px","left":"50%","margin-left":"-"+halfNewWidth+"px"});

});

This can also be triggered on resize to ensure it remains responsive. The easiest (probably not most efficient) way to do this is with the following.

$(window).on('resize', function() {

    // Same code as on load        
    var aspectRatio = 1.78;
    var video = $('#videoWithJs iframe');
    var videoHeight = video.outerHeight();
    var newWidth = videoHeight*aspectRatio;
    var halfNewWidth = newWidth/2;

    video.css({"width":newWidth+"px","left":"50%","margin-left":"-"+halfNewWidth+"px"});

});
