问题是list-style-image不显示图标，图片路径是对的,基于VScode工具

<ul1>
    <li>11</li>
    <li>11</li>
    <li>11</li>
</ul1>
<ul2>
    <li>22</li>
    <li>22</li>
    <li>22</li>
</ul2>

实测可用


<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">

    <style>
      ul1 {
        list-style-image: url('./image/diff.png');
      }
    </style>
  </head>

  <body>
    <ul1>
      <li>11</li>
      <li>11</li>
      <li>11</li>
    </ul1>
  </body>

  1. 用 ul 才行
  2. 图片地址是否写对了

我试了一下可以 你写个 ul试试 。

 ul {
         list-style-image: url(https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fci.xiaohongshu.com%2F7b58b485-7ec2-6754-e01e-b5acb512352c%3FimageView2%2F2%2Fw%2F1080%2Fformat%2Fjpg&refer=http%3A%2F%2Fci.xiaohongshu.com&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=auto?sec=1653185931&t=01451ae88bbe836e7ffcc6a5795b4555);
      }
