Question

我不知道我做错了什么。一切都很完美。这是代码。我使用Django框架和谷歌浏览器作为浏览器。我觉得我的电脑里缺少一些东西。我不知道这是什么。因为代码完美无缺。为什么我没有完美地获得导航栏？

Answer 1

首先，您在3.1.1的{{1}}和<head>底部导入了2个不同版本的jQuery，1.12。你也为<body>做了这个。

删除bootstrap.min.js和jQuery中的<head>，并将其放在bootstrap.min.js标记之前，如下所示：

</body>

然后，再试一次。希望这可以帮助。

Answer 2

Image of your page

将Django链接分别替换为http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css和http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js的bootstrap css和js，您的菜单确实显示正确。

您的Django链接可能出错了。我检查所有这些进口商品。例如，您已经两次导入bootstrap.min.js和jquery.min.js：在头部和身体中。

Answer 3

两次连接的脚本

在头部jquery.min ....和bootstrap.min ....

之前/身体

Answer 4

您需要在container-fluid之前使用nav，这样它才会填满整个屏幕，同时也会覆盖navbar。

Bootstrap第一行代码无法正常工作？
