Bootstrap 3：如何使一个居中的导航栏 [英] Bootstrap 3: How to make a centered navbar

问题描述

我看到一些黑客Bootstrap< = 2，但我使用v3，我想做一个水平行的链接，在行/容器的中心。这是我的标记：

 < div class =footer row> 
< div class =col-12> 
< ul id =menu-mainclass =nav navbar-nav> 
< li class =text-center> 
<％= link_toHome，root_path％> 
< / li> 
< li class =text-center> 
<％= link_to关于，root_path％> 
< / li> 
< li class =text-center> 
<％= link_to帮助，root_path％> 
< / li> 
< / ul> 
< / div> 
< / div> 
  

解决方案

这应该是你要找的。 / p>

这里是一个jsFiddle演示

如果你想要这是一个固定页脚，只需添加 navbar固定底部类到< nav HTML

 < nav class =navbar navbar-defaultrole =navigation> 
< div class =navbar-header> 
< button type =buttonclass =navbar-toggledata-toggle =collapsedata-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> 
< / button> 
< / div> 
 
< div class =collapse navbar-collapse navbar-ex1-collapse> 
< ul class =nav navbar-nav> 
< li class =active>< a href =＃>链接< / a>< / li> 
< li>< a href =＃>链接< / a>< / li& 
< li>< a href =＃>链接< / a>< / li& 
< / ul> 
< / div> 
< / nav> 
  

CSS

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

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;
    }
}
