css写两面翻转遇见的问题


<div class="box">
        <div class="front">你好div>
        <div class="back">打工人div>
    div>

 body {
            transform-style: preserve-3d;
            perspective: 500px;
        }
        
        .box {
            position: relative;
            width: 200px;
            height: 200px;
            margin: 100px auto;
            transition: all 0.5s;
            transform-style: preserve-3d;
        }
        
        .box:hover {
            transform: rotateY(180deg);
        }
        
        .front,
        .back {
            position: absolute;
            top: 0;
            left: 0;
            width: 100%;
            height: 100%;
            border-radius: 50%;
            text-align: center;
            line-height: 200px;
            color: #fff;
            font-size: 50px;
        }
        
        .front {
            background-color: red;
            z-index: 1;
        }
        
        .back {
            background-color: pink;
            transform: rotateY(180deg);
        }

浏览器调试后不能实现鼠标经过的时候，打工人字样出现，请求懂的人帮忙看看

大概就是上面的样子


body {
      transform-style: preserve-3d;
      perspective: 500px;
    }
    .box {
      position: relative;
      width: 200px;
      height: 200px;
      margin: 100px auto;
      transition: all 0.5s;
      transform-style: preserve-3d;
    }
    .box:hover {
      transform: rotateY(180deg);
    }
    .front,
    .back {
      position: absolute;
      top: 0;
      left: 0;
      width: 100%;
      height: 100%;
      border-radius: 50%;
      text-align: center;
      line-height: 200px;
      color: #fff;
      font-size: 50px;
    }
    .front {
      background-color: red;
      z-index: 1;
    }

    .front:hover{
      display: none !important;
    }

    .back {
      background-color: pink;
      transform: rotateY(180deg);
    }
    .back:hover{
      display: none !important;
    }
