<style>#maomao{position:fixed;bottom:40px;right:-5px;width:57px;height:70px;background-image:url(https:///cdn.mengdo.cn/wp-content/plugins/zibll_Add_ons/assets/svg/16676542890674744ca9d724add38.svg);background-position:center;background-size:cover;background-repeat:no-repeat;transition:background .3s;z-index:1000000}#maomao:hover{background-position:60px 50%;}</style>
<div id="maomao" onmouseout="duoMaomao()" style="bottom: 79vh;"></div>
<script>var randomNum =function(minNum,maxNum) {switch (arguments.length) {case 1:return parseInt(Math.random() *minNum + 1,10);break;case 2:return parseInt(Math.random() *(maxNum - minNum + 1) + minNum,10);break;default:return 0;break;};};var duoMaomao =function() {var maomao =$('#maomao');maomao.css('bottom',randomNum(1,90) + 'vh');};</script>
