通过原生JS，点击事件，鼠标按下、鼠标抬起和鼠标移动事件，实现3d立方体的拖动旋转，并将旋转角度实时的反应至界面上显示。
实现原理：通过获取鼠标点击屏幕时的坐标和鼠标移动时的坐标，来获得鼠标在X轴、Y轴移动的距离，将距离实时赋值给transform属性
从而通过改变transform：rotate属性值来达到3d立方体旋转的效果
HTML代码块：
<body><input type="button" value="点击散开"/><input type="text" value=""/>//X轴旋转角度<input type="text" value=""/>//Y轴旋转角度<input type="text"/><div><div><span></span><span></span><span></span><span></span><span></span><span></span></div></div></body>
CSS代码块：
<style>body{cursor: url("img/openhand1.png"),auto;}.big_box{width: 500px;height: 500px;margin: 200px auto;}.box{-webkit-transform-style: preserve-3d;-moz-transform-style: preserve-3d;-ms-transform-style: preserve-3d;transform-style: preserve-3d;transform-origin:100px 100px 00px;position: relative;transform: rotatex(0deg) rotatey(0deg) rotatez(0deg)scale3d(0.7,0.7,0.7);}.box span{transition: all 1s linear;}span{display: block;position: absolute;width: 200px;height: 200px;box-sizing: border-box;border:1px solid #999;/*opacity: 0.7;*/text-align: center;line-height: 200px;font-size: 60px;font-weight: 700;border-radius: 12%;}.box span:nth-child(1){background-color: deepskyblue;transform-origin: left;transform: rotatey(-90deg) translatex(-100px);//左}.box span:nth-child(2){background-color: red;transform-origin: right;transform: rotatey(90deg) translatex(100px) ;//右}.box span:nth-child(3){background-color: green;transform-origin: top;transform: rotatex(90deg) translatey(-100px) ;//上}.box span:nth-child(4){background-color: #6633FF;transform-origin: bottom;transform: rotatex(-90deg) translatey(100px);//下}.box span:nth-child(5){background-color: gold;transform: translatez(-100px);//后}.box span:nth-child(6){background-color: #122b40;transform: translatez(100px);//前}.box:hover span{opacity: 0.3;}.box:hover{animation-play-state:paused;//设置动画暂停}</style> JS代码块：
