Question

这是我项目的structure。我无法在名为indexprova.jsp文件的jsp文件中应用名为cover.css的css文件。谁能帮我？我失去了很多时间。提前致谢。我附加了css代码，jsp文件和图像，以便更容易理解。

我认为你的道路完全错了。这应该有效../../resources/css/cover.css

通常在这种情况下我的调试过程是这样的：

找出你所在的目录：移动您的cover.css文件并检查<link href="cover.css">何时起作用。首先将css文件移动到jsp文件所在的目录。
将您的css文件向上移动一个目录并检查<link href="../cover.css">
将css文件移动到目标目录并找出路径。

我用你的文件制作了测试项目，它工作正常。检查控制台中是否有任何内容。

应用外部CSS文件时出现问题
