今天要给大家带来另外一款CSS3 3D立方体动画，尤其在DEMO2中可以看到，鼠标滑过立方体后，它将会被打开，从里面弹出另外一个小立方体，动画效果非常酷，非常逼真。
实现的代码。
html代码：
<div class="content bgcolor-1">
<h2 class="center">
Depth Cube</h2>
<div style="height: 300px; margin-top: 40px;">
<div class="cube-wrap">
<div class="cube depth">
<div class="front-pane">
front</div>
<div class="back-pane">
back</div>
<div class="top-pane">
top</div>
<div class="bottom-pane">

<div class="left-pane">

<div class="right-pane">

</div>
</div>
</div>
<h2 class="center">
