可以拖动立方体3D效果代码实例
分类：实例代码
本章节分享一段代码实例，它实现了可以拖动的立方体3D效果。
代码实例如下:

position: relative;
margin: 100px auto;
transform-style: preserve-3d;
transform: perspective(800px) rotateX(0deg) rotateY(0deg);
}
#div1 div {

}
#div1 .front {
transform: translateZ(100px);
}
#div1 .back {
transform: translateZ(-100px);
}

}
#div1 .bottom {
transform: rotateX(-90deg) translateZ(100px);
}
</style>
