jquery - 在 React 组件中应用 sass css 时遇到问题

Question

我是 web 开发的新手如果不能正确解释问题，请发表评论，这样至少我可以告诉更多。

如果有人能给我一点帮助，我将不胜感激

我有一个 HTML 结构，我试图在其中应用一些 CSS，但由于某种原因无法正常工作。

我在 jsfiddle 中检查了相同的 HTML 和 CSS和 Code-pen 它工作得很好但是当我在我的 react 组件中应用同样的东西时它没有显示任何东西

我的代码:

/*

.wizard,
.tabcontrol {
  display: block;
  width: 100%;
  overflow: hidden;
}

.wizard a,
.tabcontrol a {
  outline: 0;
}

.wizard ul,
.tabcontrol ul {
  list-style: none !important;
  padding: 0;
  margin: 0;
}

.wizard ul>li,
.tabcontrol ul>li {
  display: block;
  padding: 0;
}

您必须将 css 文件链接到 HTML 文档。您可以使用 custom.css 是您编写样式的 css 文件。它适用于 jsfiddle，因为我们不必定义 css 文件和 HTML 文档之间的链接
