Bootstrap 3: How to make a centered navbar
提问by emersonthis
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:
我已经看到了 Bootstrap <=2 的一些技巧，但我使用的是 v3，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="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>

This should be exactly what you are looking for.
这应该正是您正在寻找的。
If you want this as a fixed-footer, just add navbar-fixed-bottomclass to the <nav class="navbar navbar-default" role="navigation">element.
如果您希望将其作为固定页脚，只需navbar-fixed-bottom向<nav class="navbar navbar-default" role="navigation">元素添加类即可。

Similar to @Adam's suggestion, I see that this basically works:
与@Adam 的建议类似，我看到这基本上有效：
<div class="footer row">
<ul id="menu-main" class="list-inline text-center">
<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>
<li class="text-center">
<%= mail_to "[email protected]", "Contact" %>
</li>
</ul>
</div>
However, it won't collapse on smaller widths like a navbar. It would be nice to maintain this functionality if someone knows how.
但是，它不会像导航栏那样在较小的宽度上折叠。如果有人知道如何维护此功能会很好。
