昨晚用CSS3实现了几种常见的Loading效果，虽然很简单，但还是分享一下，顺便也当是做做笔记……

第一种效果

代码如下：

<div class="loading">
 <span></span>
 <span></span>
 <span></span>
 <span></span>
 <span></span>
</div>

.loading{
 width: 80px;
 height: 40px;
 margin: 0 auto;
 margin-top:100px;
 }
 .loading span{
 display: inline-block;
 width: 8px;
 height: 100%;
 border-radius: 4px;
 background: lightgreen;
 -webkit-animation: load 1s ease infinite;
 }
 @-webkit-keyframes load{
 0%,100%{
 height: 40px;
 background: lightgreen;
 }
 50%{
 height: 70px;
 margin: -15px 0;
 background: lightblue;
 }
 }
 .loading span:nth-child(2){
 -webkit-animation-delay:0.2s;
 }
 .loading span:nth-child(3){
 -webkit-animation-delay:0.4s;
 }
 .loading span:nth-child(4){
 -webkit-animation-delay:0.6s;
 }
 .loading span:nth-child(5){
 -webkit-animation-delay:0.8s;
 }

第2种效果：

代码如下：

<div class="loading">
 <span></span>
</div>

.loading{
 width: 150px;
 height: 4px;
 border-radius: 2px;
 margin: 0 auto;
 margin-top:100px;
 position: relative;
 background: lightgreen;
 -webkit-animation: changeBgColor 1.04s ease-in infinite alternate;
 }
 .loading span{
 display: inline-block;
 width: 16px;
 height: 16px;
 border-radius: 50%;
 background: lightgreen;
 position: absolute;
 margin-top: -7px;
 margin-left:-8px;
 -webkit-animation: changePosition 1.04s ease-in infinite alternate;
 }
 @-webkit-keyframes changeBgColor{
 0%{
 background: lightgreen;
 }
 100%{
 background: lightblue;
 }
 }
 @-webkit-keyframes changePosition{
 0%{
 background: lightgreen;
 }
 100%{
 margin-left: 142px;
