效果

思路

设置 3 层元素，最上层元素使用 clip-path 裁剪成圆，hover 改变圆大小，添加过渡效果。

实现代码

      .avatar {

        background-size: cover;
        height: 200px;
        width: 200px;
        border-radius: 50%;
        cursor: pointer;
        position: relative;
      }

      .avatar::after,
      .avatar::before {
        content: "";
        position: absolute;
        inset: 0;
        border-radius: 50%;
      }

      .avatar::before {
        background: rgba(0, 0, 0, 0.5);
      }

      .avatar::after {
        background: inherit;
        clip-path: circle(0% at 50% 50%);
        transition: 0.3s;
      }

      .avatar:hover::after {
        clip-path: circle(50% at 50% 50%);
      }
    </style>
  </head>
  <body>
