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：
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; background: lightblue;
}
}第3-5种效果：
代码如下：

} .loading div:nth-child(3){ -webkit-transform: rotate(240deg);
} .loading div:nth-child(2) span{ -webkit-animation-delay: 1s;
} .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。
