思路:
一个外层盒子设置背景;一个内层盒子设置宽高背景,并设置animate让盒子移动
demo:
css部分:
@keyframes mymove {from{left:0px;}to{left:70px;}}.father{background: #748096;border-radius:5px;position: relative;top: 70px;left: -5px;}.moveson {width:20px;height:8px;background:#a0e80c;border-radius: 5px;animation:mymove 2s linear infinite;position:relative;}
html部分:
<div class="father"><div class="moveson"></div></ediv>
