Question

我找到了一个纯CSS横幅滑块，可以在代码笔中很好地工作。我已经将HTML和CSS的代码复制到了一页，但是它不起作用。所有图像都是外部的，并且可用。它没有任何Js等，只有html和css。您可能会在这里{@ 3}看到它的完美表现。

Answer 1

您的html

标记必须位于代码的开头，才能使css部分正常运行。

Answer 2

尝试添加此CSS链接。

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/10up-sanitize.css/8.0.0/sanitize.min.css">

这也是SCSS Codepen，而不是CSS。如果要让CSS工作，则必须对其进行转换

仅CSS幻灯片不显示图片
