You could try using this tutorial: CSS Background Animation

@keyframes animatedBackground {
    0% { background-position: 0 0; }
    100% { background-position: -300px 0; }
}
@-moz-keyframes animatedBackground {
    0% { background-position: 0 0; }
    100% { background-position: -300px 0; }
}
@-webkit-keyframes animatedBackground {
    0% { background-position: 0 0; }
    100% { background-position: -300px 0; }
}
@-ms-keyframes animatedBackground {
    0% { background-position: 0 0; }
    100% { background-position: -300px 0; }
}
@-o-keyframes animatedBackground {
    0% { background-position: 0 0; }
    100% { background-position: -300px 0; }
}

html { 
    width: 100%; 
    height: 100%; 
    background-image: url(background.png);
    background-position: 0px 0px;

    animation: animatedBackground 10s linear infinite;
    -moz-animation: animatedBackground 10s linear infinite;
    -webkit-animation: animatedBackground 10s linear infinite;
    -ms-animation: animatedBackground 10s linear infinite;
    -o-animation: animatedBackground 10s linear infinite;
}

This is an unorthodox trick.

<html>
<head>
<style>
    .img{
      width:1000px;
      height:500px;
      background:url(1.jpg) no-repeat left;
      transition:background-position 1s;
      -ms-transition:background-position 1s;
      -moz-transition:background-position 1s;
      -o-transition:background-position 1s;
      -webkit-transition:background-position 1s;    
      }
</style>
</head>
<body>
    <div class="img"></div>
    <link rel="stylesheet" type="text/css" href="style.css">
</body>
</html>

style.css:

img{
  background-position:right;

whats happening here is initially the css mentioned in the <style> is rendered. later since the external stylesheet is in the body just before </body>. So style.css is loaded after the resources in the are loaded. so there is a lag in implementation of the css which allows us to apply a css transition.

NO JAVASCRIPT, NO EVENTS still we get what we want!

I'm trying to animate a background-image, so that the image appears from right to left. I have used an image which has a greater width than the div-container, where the background is located. On start, the backgrond is the following
```
background: url(../img/zeppelin.png);
background-repeat: no-repeat;
background-position: right;
```
but when the page is loaded, I want the background to be animated, so that it is positioned left. This should take a eg. 2 seconds and only should be done one time. (the image should be positioned left afterwards).

I don't wanna use any mouse-events or pseudo-classes. Is there a way to animate it by using only CSS? I tried finding a solution with keyframes without success.
