使用纯 CSS 实现进度条，悬停问题

Question

我在关注100days of CSS Challenges。第62天卡住了。尝试用纯 css 实现进度条。

当悬停在卡片上时，我希望进度条有更大的宽度。

悬停下方不起作用，我不知道为什么。有关如何调试此类 css 问题的任何提示也会有所帮助。

使用 JS 会更容易，但我想要纯 CSS 解决方案。谢谢…………

改用这个 css 并相应地更改您的 html

   .basic:hover ~ .stats .users-bar {
      transform: scaleX(0.7);
    }

    .pro:hover ~ .stats .gb-bar {
      transform: scaleX(0.7);
    }

    .premium:hover ~ .stats .projects-bar {
      transform: scaleX(0.7);
    }
