当然也可以用哪吒官方的https://nezhadash-docs.buycoffee.top/custom-code 不过我觉得论坛佬的更好，可以随意调整大小 

<script>
    window.CustomLogo = "图片URL"; /* 自定义Logo */
    window.ShowNetTransfer  = "true"; /* 卡片显示上下行流量 */
    window.DisableAnimatedMan  = "true"; /* 关掉动画人物插图 */
    window.CustomDesc ="MJJ：白嫖至上，技术先行"; /* 自定义描述 */
</script>

<style> 
  .dark .bg-card {
   font-family: "Roboto", "Segoe UI", "Helvetica Neue", Helvetica, Arial, sans-serif;
    color: #ffffff; /* 白色，高对比度 */
    position: relative; /* 设置元素为相对定位 */
    background-color: rgba(0, 0, 0, 0.3); /* 设置背景颜色为半透明的黑色 */
    backdrop-filter: blur(5px); /* 应用毛玻璃效果，模糊度为5像素 */
    border-radius: 15px; /* 设置边框圆角为15像素 */
    //box-shadow: 0 6px 8px rgba(0, 0, 0, 0.1); /* 添加阴影效果 */
    //overflow: hidden;  /* 确保内容不会溢出容器 */
    }
  .dark .bg-card h1, .dark .bg-card h2, .dark .bg-card h3 {
    color: #ffffff; /* 保持标题的高对比度 */
  }
  .dark .bg-card p {
    color: #eeeeee; /* 段落文本稍微柔和一些 */
  }
</style>

以上是调整毛玻璃效果”//”是不喜欢的所以注释掉  默认黑色主题，白色主题把所有 .dark .bg-card 改成 .light .bg-card
