<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title></title> <style> *{ margin: 0; padding: 0; } ul{ width: 1000px; margin: 0 auto; } li{ cursor: pointer; border: 1px solid #fff; display: inline-block; width: 198px; height: 250px; float: left; overflow: hidden; background-color: #f7f7f7; position: relative; } li .fade{ font-family: "微软雅黑"; display: none; width: 320px; height: 270px; background: #090; position: absolute; left: 0px; top: 0px; z-index: 19; } li .img1{ width: 110px; height: 110px; text-align: center; position: absolute; top: 22px; right: 41px; z-index: 99; } li .img2{ width: 110px; height: 110px; text-align: center; position: absolute; top: 22px; left: -110px; z-index: 99; } li .txt1{ width: 198px; height: 100px; color: #999999; position: absolute; top: 145px; left: 0px; z-index: 99; text-align: center; } li .txt2{ width: 198px; height: 100px; color: #a9cf4f; position: absolute; top: 145px; right: -240px; z-index: 99; text-align: center; } </style> <script src="https://code.jquery.com/jquery-1.8.0.min.js"></script> </head> <body> <div> <ul> <li> <div></div> <div><img src="https://www.jb51.net/img/1.png"></div> <div><img src="https://www.jb51.net/img/1-1.png"></div> <div>啦啦啦啦啦</div> <div>是是是是是</div> </li> <li> <div></div> <div><img src="https://www.jb51.net/img/2.png"></div> <div><img src="https://www.jb51.net/img/2-2.png"></div> <div>啦啦啦啦啦</div> <div>是是是是是</div> </li> <li> <div></div> <div><img src="https://www.jb51.net/img/1.png"></div> <div><img src="https://www.jb51.net/img/1-1.png"></div> <div>啦啦啦啦啦</div> <div>是是是是是</div> </li> <li> <div></div> <div><img src="https://www.jb51.net/img/2.png"></div> <div><img src="https://www.jb51.net/img/2-2.png"></div> <div>啦啦啦啦啦</div> <div>是是是是是</div> </li> </ul> </div> <script> $(function(){ $("ul li").hover(function(){ $(this).children().stop(false,true); $(this).find(".fade").fadeIn("slow"); $(this).find(".img1").animate({right:-110},400); $(this).find(".img2").animate({left:41},400); $(this).find(".txt1").animate({left:240},400); $(this).find(".txt2").animate({right:0},400); },function(){ $(this).children().stop(false,true); $(this).find(".fade").fadeOut("slow"); $(this).find(".img1").animate({right:41},400); $(this).find(".img2").animate({left:-110},400); $(this).find(".txt1").animate({left:0},400); $(this).find(".txt2").animate({right:-240},400); }) }) </script> </body> </html>
