页面的head部分，先对接google的图标字体库，代码如下：

<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">

接着设置好页面元素的特效样式，由于代码内容较多，这里仅贴出部分代码：

* {
	font-family: 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
}

body {
	font-size: 1rem;
	background-color: #ebebeb;
	padding: 20px;
	text-align: center;
}

h1 {
	font-weight: 100;
	color: #777;
}

.main-wrapper {
	border-radius: 4px;
	background-color: white;
	padding: 20px;
	box-shadow: 0 3px 6px rgba(0, 0, 0, 0.16), 0 3px 6px rgba(0, 0, 0, 0.23);
	position: relative;
}

i.material-icons {
	font-size: 1.5rem;
	color: white;
	position: relative;
	border-radius: 50%;
	padding: 5px;
	margin: 3px;
	box-shadow: 0 1px 3px rgba(0, 0, 0, 0.12), 0 1px 2px rgba(0, 0, 0, 0.24);
	transition: color 0.2s ease, background-color 0.2s ease, transform 0.3s ease;
}

i.material-icons:after {
	content: "";
	width: 100%;
	height: 100%;
	border: solid 2px;
	transform: scale(0.8);
	position: absolute;
	top: -2px;
	left: -2px;
	border-radius: 50%;
	transition: all 0.3s ease;
}

i.material-icons:hover:after {
	transform: scale(1);
	box-shadow: 10px 0 20px rgba(0, 0, 0, 0.19), 6px 0 6px rgba(0, 0, 0, 0.23);
}

i.material-icons:nth-of-type(4) {
	background-color: #88b999;
}

i.material-icons:nth-of-type(4):hover {
	color: #88b999;
}

i.material-icons:nth-of-type(4):after {
	border-color: #88b999;
}

i.material-icons:nth-of-type(5) {
	background-color: #88b2b9;
}

i.material-icons:nth-of-type(5):hover {
	color: #88b2b9;
}

i.material-icons:nth-of-type(5):after {
	border-color: #88b2b9;
}

页面的body部分，一个div容器里面放入了多个i标签来显示图标，代码如下：

<h1>鼠标悬停旋转的图标按钮特效</h1>
<div class="main-wrapper">
	<i class="material-icons">attach_file</i>
	<i class="material-icons">settings</i>
	<i class="material-icons">refresh</i>
	<i class="material-icons">search</i>
	<i class="material-icons">explore</i>
	<i class="material-icons">public</i>
	<i class="material-icons">autorenew</i>
	<i class="material-icons">add</i>
</div>
