Video height and width for responsive website

问题

I am using the video HTML5 tag on a responsive website. I set the height and width to 100% and it works fine except in the mobile version where it's destroying the layout.

URL: omob-2.myshopify.com

<div style="height: 100%; width: 100%;"> 
<video width="100%" height="100%" autoplay>
<source src="intro_12_07_14.mp4" type="video/mp4">
</video> 
</div>

Any ideas?

On devices that don't support the video tag you would show a image instead. There is a answer for this here How can I display an image if browser does not support HTML5's <video> tag

Edit: set the width and height in the css styles instead of the video tag. Set the width only, so to keep dimensional proportion, like this.

video {
    width: 100%;
    height: auto   !important;
}

Use the CSS3 transform translate(-50%, -50%) to make the video in the center of the page:

Html Code

      <div class="video-container">
        <video autoplay loop="true" width="1280" height="720">
         <source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
       </video>
     </div>

CSS Code

.video-container {
      position: absolute;
      top: 0;
      bottom: 0;
      width: 100%;
      height: 100%;
      overflow: hidden;
    }
    .video-container video {
      /* Make video to at least 100% wide and tall */
      min-width: 100%;
      min-height: 100%;
      /* Setting width & height to auto prevents the browser from stretching or squishing the video */
      width: auto;
      height: auto;
      /* Center the video */
      position: absolute;
      top: 50%;
      left: 50%;
      -webkit-transform: translate(-50%, -50%);
              transform: translate(-50%, -50%);
    }
    body {
      background: #000;
      color: #fff;
      font-family: 'Oxygen', sans-serif;
    }
