Good day. I have tried to find a way to apply the full screen video in the background like on this page here: [spotify](https://www.spotify.com/pl/video-splash/?utm_source=spotify&utm_medium=web&utm_campaign=start). I assume it can be done in HTML5, however I am trying to follow some instructions from stackoverflow and it doesn't work for me. Obviously I don't want the timeline and other controls on the video, just simple plain video in the background.
So far I was trying to use this:

jsFiddles underneath the code

```
<style>
    #body{position:absolute; width:100%; height:100%}
    #myvideo{position:relative; top:0; left:0; width:100%; height:100%; z-index:-999;}
    #fullpage{width:80%; margin:0 auto; background-color:#900; z-index:100;}

</style>

<video width="100%" height="100%" autoplay="autoplay" id="myvideo">
  <source src="http://www.pete.dj/video/video.webm"></source>
  <source src="http://www.pete.dj/video/video.mp4"></source>
</video>

<script language="javascript">
var elem = document.getElementById("myvideo");
if (elem.requestFullscreen) {
  elem.requestFullscreen();
} else if (elem.mozRequestFullScreen) {
  elem.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen) {
  elem.webkitRequestFullscreen();
}
</script>

<div id="fullpage">
    content goes here
</div>

```

but it didn't work well. Here is what is wrong:

1. video plays full height, doesn't being stretched or resized to cover the whole width of the screen
2. video plays OK on chrome, but it doesn't on other browsers, what could be the reason? I thought html5 allows to play on all browsers. I've got a feeling it's not a matter of codecs or the files itself. Can it be caused by coding?

after I've managed to fix the issue with width of the video - then it doesn't act like a background, as scrollbars appeared. What can I do to get rid of scrollbars caused by video? I want them only if the actual #fullpage requires it. Unfortunately also #fullpage is behind the background in this case... instead of on top of it
here is a fiddle for this one: [fiddle2](http://jsfiddle.net/tucado/SSf5F/1/)

Thank you for your help and time.
