<head>
<style>
div {
    position: relative;
    height: 60px;
    width: 60px;
    background-color: red;
    -webkit-transform: rotateY(180deg);  /* Chrome, Safari, Opera */
    transform: rotateY(180deg);

#div1 {
    -webkit-backface-visibility: hidden;  /* Chrome, Safari, Opera */
    backface-visibility: hidden;

#div2 {
    -webkit-backface-visibility: visible;  /* Chrome, Safari, Opera */
    backface-visibility: visible;
}
</style>

<script>
var _hmt = _hmt || [];
(function() {
var hm = document.createElement("script");
hm.src = "//hm.baidu.com/hm.js?73c27e26f610eb3c9f3feb0c75b03925";

<p>This example shows two div elements, rotated 180 degrees, facing away from the user.</p>
<p>The first div element has the backface-visibility property set to "hidden", and should therefore be invisible.</p>

<div id="div1">DIV 1</div>
<div id="div2">DIV 2</div>

<p><strong>Note:</strong> The backface-visibility property is not supported in Internet Explorer 9 and earlier versions.</p>
