我正在实现一个导航栏，我想使用 Django 模板来实现 DRY 原则。第一张图是模板化前的样子，第二张图是模板化后的样子。 ( https://imgur.com/a/FOEqKFB )
如何让 css 文件在继承的 html 文件中正确呈现？我认为这是我没有调用 base.html 中的 CSS 文件的情况(例如:another similar answer)，但我检查了 base.html 的代码并且我已经为导航栏样式调用了 Bootstrap CDN header 。我的代码出了什么问题？
这是问题的相关代码: 基础.html

最佳答案
Bootstrap 所需的 3 个脚本位于 base.html 的 footer_javascript_site block 中，在 <body> 中标签。那是无效的 HTML。你可以简单地将它移动到 <body> 中或者看看 Where should I put <script> tags in HTML markup?有关如何将其全部放入 <head> 的建议.
