中心导航品牌和菜单介于767px和992px之间

标签： css twitter-bootstrap center

我在stackoverflow上阅读了其他问题，但我无法弄清楚（不工作），如何在移动设备的767px和992px之间居中使用导航栏菜单和徽标...

对于PC来说：

----------- simple links menu--
-- logo ------------- navmenu--

...对于小型设备＆gt; 767px和＆lt; 767px 992px应该是3行，全部居中：

＆＃13;
＆＃13; 
------ simple links menu ------
-------------- logo -----------
------------ navmenu ----------
＆＃13;
＆＃13;
＆＃13;

在767px以下它很好 - 有折叠菜单......

以下是仅针对标题导航和完整css的代码：
