css - 在元素居中后 Bootstrap 垂直折叠导航栏菜单

Question

我的 Bootstrap 导航栏有问题。我最近找到了一种将导航栏中的元素居中的方法，但事实是，当菜单折叠时，这些元素保持水平对齐而不是垂直对齐。

这是我目前拥有的:

<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，我的元素在导航栏中居中，但在折叠菜单中水平显示。我想获得一些帮助来更改它，以便恢复 Bootstrap 折叠菜单的经典行为(我的意思是垂直)，而不会在菜单未折叠时更改居中的元素。

只需在媒体查询中应用您的规则:

@media (min-width: 767px) {

}

请参阅工作示例片段。

@media (min-width: 767px) {
  .center .nav,
  .center .nav > li {
    float: none;
    display: inline-block;
    vertical-align: top;
  }
  .center .navbar-inner {
    text-align: center;
  }
  .center .dropdown-menu {
    text-align: left;
  }
}
