css3可拖动的魔方3d
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/elephant.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">
<input type="image" class="1" src="./img/cat.jpg">
<input type="image" class="2" src="./img/dog.jpg">
<input type="image" class="3" src="./img/elephant.jpg">
