Bootstrap 4 - 导航栏不会折叠

Question

I have no idea why it isn't working.我不知道为什么它不起作用。 I even tried to copy and paste the button and div tags from the examples in bootstrap's web site.我什至尝试从引导程序网站的示例中复制和粘贴按钮和 div 标签。 I thought it has something to with the social media icons part.我认为它与社交媒体图标部分有关。 I turned them into comment lines but didn't work.我把它们变成了注释行，但没有用。 Do you see my mistake?你看到我的错误了吗？

Sorry if this is a repeat.对不起，如果这是重复。 I found questions with same title but they didn't help.我发现了具有相同标题的问题，但它们没有帮助。

Thanks...谢谢...

Answer 1

You are using the class navbar-expand , which means that it never collapses.您正在使用类navbar-expand ，这意味着它永远不会折叠。 Just change it to navbar-expand-sm , and it will collapse on small screens.只需将其更改为navbar-expand-sm ，它就会在小屏幕上折叠。
