CSS3实现18种Loading效果
jopen 8年前
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; background: lightblue; } }第3-5种效果：
代码如下：
<div class="loading"> <span></span> <span></span> <span></span> <span></span> <span></span> </div>第3-5种效果的css样式分别为：
.loading{ width: 150px; height: 15px; margin: 0 auto; margin-top:100px; } .loading span{ display: inline-block; width: 15px; height: 100%; margin-right: 5px; border-radius: 50%; background: lightgreen; -webkit-animation: load 1.04s ease infinite; } .loading span:last-child{ margin-right: 0px; } @-webkit-keyframes load{ 0%{ opacity: 1; } 100%{ opacity: 0; } } .loading span:nth-child(1){ -webkit-animation-delay:0.13s; } .loading span:nth-child(2){ -webkit-animation-delay:0.26s; } .loading span:nth-child(3){ -webkit-animation-delay:0.39s; } .loading span:nth-child(4){ -webkit-animation-delay:0.52s; } .loading span:nth-child(5){ -webkit-animation-delay:0.65s; }.loading{ width: 150px; height: 15px; margin: 0 auto; margin-top:100px; } .loading span{ display: inline-block; width: 15px; height: 100%; margin-right: 5px; border-radius: 50%; background: lightgreen; -webkit-animation: load 1.04s ease infinite; } .loading span:last-child{ margin-right: 0px; } @-webkit-keyframes load{ 0%{ opacity: 1; -webkit-transform: scale(1.3); } 100%{ opacity: 0.2; -webkit-transform: scale(.3); } } .loading span:nth-child(1){ -webkit-animation-delay:0.13s; } .loading span:nth-child(2){ -webkit-animation-delay:0.26s; } .loading span:nth-child(3){ -webkit-animation-delay:0.39s; } .loading span:nth-child(4){ -webkit-animation-delay:0.52s; } .loading span:nth-child(5){ -webkit-animation-delay:0.65s; }.loading{ width: 150px; height: 15px; margin: 0 auto; position: relative; margin-top:100px; } .loading span{ position: absolute; width: 15px; height: 100%; border-radius: 50%; background: lightgreen; -webkit-animation: load 1.04s ease-in infinite alternate; } @-webkit-keyframes load{ 0%{ opacity: 1; -webkit-transform: translate(0px); } 100%{ opacity: 0.2; -webkit-transform: translate(150px); } } .loading span:nth-child(1){ -webkit-animation-delay:0.13s; } .loading span:nth-child(2){ -webkit-animation-delay:0.26s; } .loading span:nth-child(3){ -webkit-animation-delay:0.39s; } .loading span:nth-child(4){ -webkit-animation-delay:0.52s; } .loading span:nth-child(5){ -webkit-animation-delay:0.65s; }第6-8种效果：
