Edit This Code:
<!DOCTYPE html>
<html>
<head>
<style>#myDIV {
    width: 300px;
    height: 200px;
    background: red url('smiley.gif') no-repeat top left/5px 5px;
    -webkit-animation: mymove 5s infinite; /* Chrome, Safari, Opera */
    animation: mymove 5s infinite;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes mymove {
    50% {background: blue bottom right/50px 50px;}
}

/* Standard syntax */
@keyframes mymove {
    50% {background: blue bottom right/50px 50px;}
}
</style>
</head>
<body>

<p>Gradually change the background property:<p>
<div id="myDIV"></div>

<p>The background property is a shorthand property for all background properties.</p>
<p>Only background-color, background-position, and background-size are <em>animatable</em> in CSS.</p>
<p><b>Note:</b> CSS Animations do not work in Internet Explorer 9 and earlier versions.</p>
