你好，我一直在寻找没有运气的答案。
我正在寻找一种方法，使我可以轻松添加到其他页面的导航栏来清理代码。
我一直在努力做到这一点，但运气不好。希望我能在这里得到答案。
我正在使用Bootstrap库，如果那里有人可以帮助我，那将是很棒的事情。
您将在下面找到HTML代码。

使用在服务器端（最常见）或在构建时运行的模板系统（或包含系统）（可以支持仅允许静态文件的HTTP服务器）。
使用您喜欢的任何编程语言（如果要在服务器端进行操作，则受服务器支持）； PHP和运气一样普遍，Java是一种选择，我倾向于Perl（更具体地说是Template Toolkit），还有很多其他东西。对于此类工作，JavaScript变得越来越流行，并且assemble之类的工具开始可用。您可以完全使用a static site generator。
使用搜索引擎查找流行的模板语言或包含您选择的编程语言的系统。
