这是 structure我的元素。我无法在名为 indexprova.jsp 的 jsp 文件中应用名为 cover.css 的 css 文件。谁能帮我？我浪费了很多时间。提前致谢 。我附上了 css 代码、jsp 文件和图像，这样情况就更容易理解了。

最佳答案

我认为您的路径完全错误。这应该有效 ../../resources/css/cover.css

一般这种情况我的调试过程是这样的:

  1. 找出你所在的目录:移动你的 cover.css 文件并检查何时 <link href="cover.css">将工作。首先将 css 文件移动到与 jsp 文件相同的目录。
  2. 将您的 css 文件向上移动一个目录并检查 <link href="../cover.css">
  3. 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元素，它工作正常。检查控制台中是否有任何内容。 enter image description here
