原理很简单,就是几张颜色不同的波浪图来回滚动。
1、首先得准备三张图,一张是浅黄色的背景图loading_bg.png,一张是深红色的图loading.png,最后一张为bolang.png。
2、css代码:
body{background:#ffe894;} .loading_bg{width:113px; height:111px;background:url(loading_bg.png) no-repeat left top;margin:30px auto;} .loading{width:113px; height:111px;position:relative; -webkit-mask-image:url(loading.png);} .show{ width:120px; height:187px; position:absolute; left:0; top:40px; animation:sploosh 3s ease-in-out both infinite; -webkit-animation:sploosh 3s ease-in-out both infinite; background-image: url(bolang.png); } .show_01{-webkit-animation-delay: -0.8s; animation-delay: -0.8s; opacity:0.2;} .show_02{-webkit-animation-delay: -1.6s; animation-delay: -1.6s; opacity:0.4;} .show_03{-webkit-animation-delay: -2.4s; animation-delay: -2.4s; opacity:0.6;} .show_04{-webkit-animation-delay: -3.2s; animation-delay: -3.2s; opacity:0.8;} @-webkit-keyframes sploosh{ 0% {background-position: 0 bottom;} 100% {background-position: 200px bottom;} } @keyframes sploosh{ 0% {background-position: 0 bottom;} 100% {background-position: 200px bottom;} }3、html代码:
<div class="loading_bg"> <div class="loading"> <div class="show_01 show"></div> <div class="show_02 show"></div> <div class="show_03 show"></div> <div class="show_04 show"></div> </div> </div>
