我无法让Bootstrap 3.3.7 navbar-fixed-top正常工作

Question

I've been using Bootstrap navbars for five years now. 我使用Bootstrap导航栏已有五年了。 This is the first time I haven't been able to make it work. 这是我第一次无法使其工作。 I have even copied the html right from the Bootstrap site and I can't get it to work in any browser nor in dreamweaver. 我什至直接从Bootstrap网站复制了html，但我无法在任何浏览器或Dreamweaver中使用它。 I have been searching for a solution for two days now and cannot find one anywhere. 我一直在寻找解决方案两天了，找不到任何地方。

Answer 2

It looks like you used container instead of container-fluid 看起来您使用的是container而不是container-fluid

The W3 documentation should work. W3文档应该可以工作。
