Bootstrap 3:如何制作居中的导航栏 [英] Bootstrap 3: How to make a centered navbar

问题描述

我已经看到 Bootstrap <=2 的一些技巧，但我使用的是 v3，并且我想制作一排以行/容器为中心的水平链接.这是我的标记:

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

解决方案

这应该正是您要找的.

这是一个jsFiddle Demo

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.

HTML

<div class="navbar-header"><button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"><span class="sr-only">切换导航</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span>

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

</nav>

CSS

@media(最小宽度:768px){.navbar-导航{浮动:无；边距:0 自动；显示:表；表格布局:固定；}}

I've seen some hacks for Bootstrap <=2 but I'm using v3 and I want to make a horizontal row of links that are centered within the row/container. Here's my markup:

<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>

解决方案

This should be exactly what you are looking for.

Here is a jsFiddle Demo

If you want this as a fixed-footer, just add navbar-fixed-bottom class to the <nav class="navbar navbar-default" role="navigation"> element.

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;
    }
}
