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1种效果：

loading1

代码如下：

.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：

loading2

代码如下：

.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; background: lightblue; } }
