CSS3实现18种Loading效果

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：

<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：

        }        .loading div:nth-child(3) span{            -webkit-animation-delay: 2s;
        }

PS：CSS样式代码其实很多重复，主要就是动画不一样，但为了方便以后直接拿来用，就先不整理了。
