Bootstrap导航栏更正

Question

我遇到了导航问题，导航栏中出现导航栏。

1. 搜索表单后面有很多未使用的空间，我怎么能摆脱它？
2. 我可以使导航栏尽快崩溃，它会使2行导航栏？

Answer 1

的导航栏会根据您设置的屏幕尺寸崩溃。现在你链接到CDN，所以你必须重写CSS的@media部分。

额外空间也需要被覆盖。它看起来像这里的样式表：

@media (min-width: 768px) 
navbar.less:385 
.navbar-right { 
    float: right!important; 
    margin-right: -15px; 
}
