Jquery 导航栏下方的引导搜索栏

我有一个使用引导定义的导航栏，如下所示：

        <nav class="navbar navbar-default navbar-fixed-top" role="navigation">
            <div class="navbar-inner">
                <div class="container">

由于您的第一个导航栏获得了
.navbar固定顶部
，因此您可以在CSS代码中设置
主体{padding top:70px；}
，以防止重叠，另请参见：

固定导航栏将覆盖您的其他内容，除非您添加
填充到顶部。尝试你自己的价值观或使用我们的
下面的片段。提示：默认情况下，导航栏的高度为50px

我还发现您的搜索框（包装在
输入组clearfix
中）没有一个
float:left
（用于更大的屏幕宽度）将您的第一个导航栏分成两行。
在其他情况下，导航栏也会分成两行：

最后，您还应该读到：
谢谢，我感谢您的真正帮助！
