主要用到知识点：
•css3 3d转换 •原生js鼠标拖动事件
•display:grid 布局
实现的功能
•3d魔方 可点击，可拖动
•直接看效果
html：
<div class="container">
<div class="box defaul">
<div class="pic"><img src="./img/cat.jpg" alt=""></div>
<div class="pic"><img src="./img/dog.jpg" alt=""></div>

<div class="pic"><img src="./img/lion.jpg" alt=""></div>
<div class="pic"><img src="./img/rabbit.jpg" alt=""></div>
<div class="pic"><img src="./img/monkey.jpg" alt=""></div>
</div>
</div>
<h1>点击下面的图片按钮切换</h1>
<div class="btn">

//鼠标拖动效果
var xN = 10, yN = 15;
