如何在模板中进行样式设置，因为我的样式在 Django 模板中不起作用？

Question

我从 github 下载了代码并运行了它的服务器，它向我显示了带有如下样式模板的输出：

但是两天后，我的样式出错了，同样在我自己的项目中，我正在使用样式，但现在，它给了我这样的视图：

表格显示如下：

我不知道为什么它在正常工作前两天就这样了，还有我下载的 github 项目，它的样式也不起作用，即使我没有对下载的项目进行任何更改。首先它正在工作。现在，在我下载的项目模板和我自己的快速旅行项目中，这些模板都无法正常工作。

静态文件有错误吗？还是 CSS 样式？我该如何解决这个问题？

这是我的模板代码：
