css3实现的动态月食效果代码实例:
本章节分享一段代码实例，它利用CSS3实现了动态的月食效果。
动画其实比较简单简短，需要的朋友可以自行做一下分析，这里就不多介绍了。
代码实例如下:
<!DOCTYPE html><html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>蚂蚁部落</title> <style type="text/css">*{ margin:0; padding:0;}body{ background-color: #000;}.moonback{ width:600px; height:600px; background-color:#000; margin:0 auto; position: relative;}.moonback::before{ content:","; display:block; position:absolute; left:200px; top:100px; width:200px; height:200px; background-color:#ff0; border-radius:100px;}.moonback::after{ content:" "; display:block; position:absolute; left:26px; top:0px; width:200px; height:200px; background-color:#000; border-radius:100px; -webkit-animation:12s dog linear infinite; -moz-animation:12s dog linear infinite; animation:12s dog linear infinite; -webkit-animation-fill-mode:forwards; -moz-animation-fill-mode: forwards; animation-fill-mode: forwards;} @-webkit-keyframes dog{ 0%{ left:27px; top:0px; } 100%{ left:399px; top:216px; }}@-moz-keyframes dog { 0%{ left:27px; top:0px; } 100%{ left:399px; top:216px; }}@keyframes dog{ 0%{ left:27px; top:0px; } 100%{ left:399px; top:216px; }}.star{ position:absolute;}.star::before{ content:"★"; display:block; position:absolute; left:10px; top:20px; width:auto; height:auto; color:#fff; -webkit-transform:scale(0.5); -moz-transform:scale(0.5); transform:scale(0.5); -webkit-animation:1s starlight linear infinite; -moz-animation:1s starlight linear infinite; animation:1s starlight linear infinite; -webkit-animation-fill-mode:forwards; -moz-animation-fill-mode: forwards; animation-fill-mode: forwards;}.star::after{ content:"★"; display:block; position:absolute; left:40px; top:120px; width:auto; height:auto; color:#fff; -webkit-transform:scale(0.5); -moz-transform:scale(0.5); transform:scale(0.5); -webkit-animation:2s starlight linear infinite; -moz-animation: 2s starlight linear infinite; animation: 2s starlight linear infinite;} @-webkit-keyframes starlight{ 0%{ -webkit-transform:scale(0.5); } 100%{ -webkit-transform:scale(0.1); }}@-moz-keyframes starlight{ 0%{ -moz-transform:scale(0.5); } 100%{ -moz-transform:scale(0.1); }}@keyframes starlight{ 0%{ transform:scale(0.5); } 100%{ transform:scale(0.1); }} </style> </head> <body> <div class="content"> <div class="moonback"> <div class="star" style="top:20px;right:220px;"></div> <div class="star" style="top:50px;right:120px;"></div> <div class="star" style="top:190px;left:20px;"></div> <div class="star" style="top:220px;left:50px;"></div> </div> </div> </body></html>上面的代码实现了我们的要求，更多内容可以参阅相关阅读。
