50% {background-color: lightgreen; left: 550px; top: 80px;}
75% {background-color: lightblue; left: 0px; top: 80px;}
100% {left: 0px; top: 0px;}
}
</style>
<script>
function changeDir(){
document.getElementById("DIV1").style.animationDirection="alternate-reverse"
}
</script>
</head>
<body>
<h1>animationDirection property example</h1>
