javascript - Why doesn't the one that automatically changes the background of the two scripts execute?

Some time ago, I confessed that the webpage was very interesting, so I tried to watch the video and wrote the code, but why was the script for automatically changing the background not executed? Please give me some advice## Only one of the two scripts has been implemented

<!doctype html>

    #bg_body{
        background:url(image/1.jpg) no-repeat center #eee;
        background-size:cover;
       /*  background-attachment:fixed;
        height:1000px; */
    }
    /*start top*/
    .top{width:400px;height:100px;margin:60px auto;font-size:30px;font-family:"华文行楷";color:#fff;}
    /*end top*/

    /*start box*/
    .box{width:310px;height:310px;margin:auto;perspective:800px;}
    .box .pic{position:relative;transform-style:preserve-3d;animation:play 10s linear infinite;}/*匀速 无线运行*/
    .box ul li{list-style:none;position:absolute;top:0;left:0;}
