span是内联元素，display:inline-block 内联元素 可以设定宽<br/>
span设定background，设定背景图居中center center<br/>
鼠标滑过的时候，三个图片都是一样的动画，所以，动画放在link:hover中<br/>
鼠标滑过的icon  link .icon:hover<br/><br/>
Transform 定义和用法<br/>
    transform属性向元素应用2D或3D转换。该属性允许我们对元素进行旋转、缩放、移动或倾斜。<br/>
rotate(angle)旋转<br/>
scale缩放<br/>
兼容性：IE10 Opera支持transform<br/>
IE9 -ms-transform<br/>
Safari和Chrome支持-webkit-transform<br/>
Opera只支持2D转换<br/>
FF -moz-transform<br/>
要让动画有效果，需要Transition属性<br/>
transition属性时一个简写属性，用于设置四个过渡属性：<br/>
transition-property、transition-duration、transition-timing-function、transition-delay<br/>
语法：
transition:property duration timing-function delay;<br/>
<li>transition-property:规定设置过渡效果的CSS属性的名称    过渡宽 transition:width 或 transition-property:width</li>
<li>transition-duration:规定完成过渡效果需要多少秒毫秒</li>
<li>transition-timing-function:规定速度效果的速度曲线  ease-out减速 ease慢动作开始变快又变慢</li>
<li>transition-delay:定义过渡效果何时开始</li>
<br/><br/>
box-sizing:border-box;如果你将一个元素的width设为100px,那么这100px会包含其它的border和padding，内容区的实际宽度会是width减去border + padding的计算值。<br/>
    opacity:0;透明度0<br/>
