一、知识准备

css3属性：

[perspective][]

[transition][]

[transform][]

[transform-style][]

[backface-visibility][]

[transform-origin][]

[更多][Link 1]

二、开始动手

首先创建一个HTML结构，如下所示：

接下来更改基本的样式，先将<li>标签基本样式去掉，同时使<a>能自定义宽度、高度。

.nav-menu > li {
    	display: inline;
    	float: left;
    }
    .nav-menu li a {
    	color: #fff;
    	display: block;
    	text-decoration: none;
    	/*font-smoothing:使字体变清晰*/
    	-webkit-font-smoothing: antialiased;
    	-moz-font-smoothing: antialiased;
    	font-smoothing: antialiased;
    	line-height: 20px;
    	/*line-height：使字垂直居中*/
    	font-size: 20px;
    	padding: 15px 30px 15px 31px;
    }

将下来我们就要创建3D效果了，选项就激动呢\\(≧▽≦)/

平时浏览器渲染都是2D的，如果要程序3D效果，肯定要先创建一个3D舞台布景，让它在上面动起来

.three-d {
    
    	/* 设置3D舞台布景 */
    	/*perspective 属性定义 3D 元素距视图的距离，越大越远*/
    	-webkit-perspective: 200px;
    	-moz-perspective: 200px;
    	-ms-perspective: 200px;
    	-o-perspective: 200px;
    	perspective: 200px;			  /*设置3D舞台布景过渡效果*/
    	-webkit-transition: all .07s linear;
    	-moz-transition: all .07s linear;
    	-ms-transition: all .07s linear;
    	-o-transition: all .07s linear;
    	transition: all .07s linear;
    	position: relative;
    }

有了舞台之后，表演什么呢？这就需要我们给它编排了\\(^o^)/~

/*设置3D前，与3D后变形效果*/
    .front {
    	-webkit-transform: rotatex(0deg) translatez(25px);
    	-moz-transform: rotatex(0deg) translatez(25px);
    	-ms-transform: rotatex(0deg) translatez(25px);
    	-o-transform: rotatex(0deg) translatez(25px);
    	transform: rotatex(0deg) translatez(25px);
    }
    .back {
    	-webkit-transform: rotatex(-90deg) translatez(25px);
    	-moz-transform: rotatex(-90deg) translatez(25px);
    	-ms-transform: rotatex(-90deg) translatez(25px);
    	-o-transform: rotatex(-90deg) translatez(25px);
    	transform: rotatex(-90deg) translatez(25px);
    	color: #FFE7C4;
    }
    .front, .back {
    	display: block;
    	width: 100%;
    	height: 100%;
    	position: absolute;
    	top: 0;
    	left: 0;
    	padding: 15px 30px 15px 31px;
    	color: white;
    	-webkit-pointer-events: none;
    	-moz-pointer-events: none;
    	-ms-pointer-events: none;
    	-o-pointer-events: none;
    	pointer-events: none;
    	-webkit-box-sizing: border-box;
    	box-sizing: border-box;
    	background: -webkit-linear-gradient(rgb(63, 184, 211), rgb(25, 137, 185), rgb(6, 91, 158));
    	background: -o-linear-gradient(rgb(63, 184, 211), rgb(25, 137, 185), rgb(6, 91, 158));
    	background: -moz-linear-gradient(rgb(63, 184, 211), rgb(25, 137, 185), rgb(6, 91, 158));
    	background: linear-gradient(rgb(63, 184, 211), rgb(25, 137, 185), rgb(6, 91, 158));
    	filter: alpha(opacity=80);
    }

舞台准备好了，舞蹈也编排好了，但是好像还是缺了点什么？(⊙v⊙)嗯，对了，没有Music怎么行呢，有音乐才能跟着节拍起舞啊...

.three-d-box {
    
    	/*给3D舞台中“.three-d-box”设置过渡与变形效果*/
    	-webkit-transition: all .3s ease-out;
    	-moz-transition: all .3s ease-out;
    	-ms-transition: all .3s ease-out;
    	-o-transition: all .3s ease-out;
    	transition: all .3s ease-out;
    	-webkit-transform: translatez(-25px);
    	-moz-transform: translatez(-25px);
    	-ms-transform: translatez(-25px);
    	-o-transform: translatez(-25px);
    	transform: translatez(-25px);
    	-webkit-transform-style: preserve-3d;
    	-moz-transform-style: preserve-3d;
    	-ms-transform-style: preserve-3d;
    	-o-transform-style: preserve-3d;
    	transform-style: preserve-3d;
    	-webkit-pointer-events: none;
    	-moz-pointer-events: none;
    	-ms-pointer-events: none;
    	-o-pointer-events: none;
    	pointer-events: none;
    	position: absolute;
    	top: 0;
    	left: 0;
    	display: block;
    	width: 100%;
    	height: 100%;
    }
