纯CSS仿windows系统loading效果

今天分享的css3案例模仿了window系统下的loading效果
里面最关键的地方使用了css3 animation的delay属性以及
贝塞尔曲线（cubic-bezier）的过渡效果，如下所示

span[class*="l-"] {
 height: 8px; width: 8px;
 background: #fff;
 display: inline-block;
 margin: 12px 2px;
 
 border-radius: 100%;
 -webkit-border-radius: 100%;
 -moz-border-radius: 100%;
 
 -webkit-animation: loader 4s infinite;
 -webkit-animation-timing-function: cubic-bezier(0.030, 0.615, 0.995, 0.415);
 -webkit-animation-fill-mode: both;
 -moz-animation: loader 4s infinite;
 -moz-animation-timing-function: cubic-bezier(0.030, 0.615, 0.995, 0.415);
 -moz-animation-fill-mode: both;
 -ms-animation: loader 4s infinite;
 -ms-animation-timing-function: cubic-bezier(0.030, 0.615, 0.995, 0.415);
 -ms-animation-fill-mode: both;
 animation: loader 4s infinite;
 animation-timing-function: cubic-bezier(0.030, 0.615, 0.995, 0.415);
 animation-fill-mode: both;
}

span.l-1 {-webkit-animation-delay: 1s;animation-delay: 1s;-ms-animation-delay: 1s;-moz-animation-delay: 1s;}
span.l-2 {-webkit-animation-delay: 0.8s;animation-delay: 0.8s;-ms-animation-delay: 0.8s;-moz-animation-delay: 0.8s;}
span.l-3 {-webkit-animation-delay: 0.6s;animation-delay: 0.6s;-ms-animation-delay: 0.6s;-moz-animation-delay: 0.6s;}
span.l-4 {-webkit-animation-delay: 0.4s;animation-delay: 0.4s;-ms-animation-delay: 0.4s;-moz-animation-delay: 0.4s;}
span.l-5 {-webkit-animation-delay: 0.2s;animation-delay: 0.2s;-ms-animation-delay: 0.2s;-moz-animation-delay: 0.2s;}
span.l-6 {-webkit-animation-delay: 0;animation-delay: 0;-ms-animation-delay: 0;-moz-animation-delay: 0;}
