具有居中项目后,Bootstrap垂直折叠导航栏菜单

我的bootstrap导航栏有问题。我最近找到了一种在导航栏中居中项目的方法,但事实是当菜单折叠时,这些项目会保持水平对齐而不是垂直对齐。

这就是我现在所拥有的:

<div class="container-fluid">
<nav class="navbar navbar-inverse navbar-fixed-top fixfollow center">
    <div class="navbar-inner">
        <div class="container">

            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <a class="navbar-brand hidden-lg" href="/"><i class="fa fa-home fa-lg"></i></a>
            </div>
            <div class="collapse navbar-collapse">
                <ul class="nav navbar-nav">

                    <li>
                        <a class="navbar-brand visible-lg" href="/"><i class="fa fa-home fa-lg"></i></a>
                    </li>
                    <li>
                        <a href="/link">link</a>
                    </li>
                    <li>
                        <a href="/link">link</a>
                    </li>
                    <li>
                        <a href="/link">link</a>
                    </li>
                    <li>
                        <a href="/link">link</a>
                    </li>
                    <li>
                        <a href="/link">link</a>
                    </li>
                </ul>
            </div>
        </div>

    </div>
</nav>

和重要的CSS:

.center .nav,
 .center .nav > li
{
    float:none;
    display:inline-block;
    /*display:inline; /* ie7 fix */
    /*zoom:1; /* hasLayout ie7 trigger */
    vertical-align: top;
}


.center .navbar-inner {
    text-align:center;
}

.center .dropdown-menu {
    text-align: left;
}

有了这个,我的项目在导航栏中居中,但在collopased菜单中水平显示。我希望有一些帮助来改变它,以便在没有折叠菜单的情况下取回引导折叠菜单的经典行为(我的意思是垂直)而不改变居中的项目。

  .center .nav,
  .center .nav > li {

  .center .dropdown-menu {
    text-align: left;
  }

也许,尝试通过带有下拉菜单的 .navbar-header 更改类 .dropdow-menu (如何取消设置)。
