我想使用这个模板 http://getbootstrap.com/docs/4.0/examples/pricing/
但它不起作用。我看到有很多 scss 文件，但我不知道如何包含/编译/无论它们是什么。
您无需担心任何 Sass 文件。您可以从下面复制并粘贴我的模板...
实际上，这不是我的模板，而是您要链接到的模板。
如您所见，它工作得很好(单击下面的"运行代码片段"按钮)。
您在官方网站上看到的"scss文件"实际上只是对这些文件的maps，这对于调试和自定义非常方便。但是你不需要担心这些，因为你可以做任何你想做的事情，而无需接触scss文件。这些 Sass 文件仅适用于高级用户。
话虽如此，学习 Sass 当然非常方便，强烈推荐，但您可以使用 Bootstrap 4 完成几乎所有您需要的事情，而无需接触 Sass。只是为了让了解 Sass，您可以成为 Bootstrap 4 MASTER，而不是仅仅达到 Bootstrap 4忍者级别作为最高级别。如果这是有道理的。
