Bootstrap 3:如何制作居中的导航栏

Question

我已经看到Bootstrap <= 2的一些黑客,但我正在使用v3,我想制作一个水平行的链接,在行/容器中居中.这是我的标记:

<div class="footer row">    
    <div class="col-12">                
        <ul id="menu-main" class="nav navbar-nav">
            <li class="text-center">
                <%= link_to "Home", root_path  %>
            </li>
            <li class="text-center">
                <%= link_to "About", root_path  %>          
            </li>
            <li class="text-center">
                <%= link_to "Help", root_path  %>           
            </li>
        </ul>
    </div>  
</div>

Answer 1

这应该是你正在寻找的.

这是一个jsFiddle演示

如果您希望将其作为固定页脚,只需将navbar-fixed-bottom类添加到<nav class="navbar navbar-default" role="navigation">元素中即可.

HTML

<nav class="navbar navbar-default" role="navigation">
   <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
         <span class="sr-only">Toggle navigation</span>
         <span class="icon-bar"></span>
         <span class="icon-bar"></span>
         <span class="icon-bar"></span>
      </button>
   </div>

   <div class="collapse navbar-collapse  navbar-ex1-collapse">
      <ul class="nav navbar-nav">
         <li class="active"><a href="#">Link</a></li>
         <li><a href="#">Link</a></li>
         <li><a href="#">Link</a></li>
      </ul>
  </div>
</nav>

CSS

@media (min-width: 768px){
    .navbar-nav{
        float:none;
        margin: 0 auto;
        display: table;
        table-layout: fixed;
    }
}

Answer 2

.nav.navbar-nav {
  display: flex;
  justify-content: center;
  flex-wrap: wrap;
}

@media (min-width: 768px) {
  .navbar-nav {
    float: none;
  }
}

    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />

    <nav class="navbar navbar-default">
      <div class="container-fluid">
        <ul class="nav navbar-nav">
          <li><a href="#">Home</a></li>
          <li><a href="#">About</a></li>
          <li><a href="#">Help</a></li>
        </ul>
      </div>
    </nav>
