Bootstrap: navbar column issues
提问by Chris Schmitz
I'm trying to build a navbar in Bootstrap using the column system and I'm running into some problems that I'm not sure what I'm doing wrong.
我正在尝试使用列系统在 Bootstrap 中构建导航栏，但遇到了一些我不确定自己做错了什么的问题。
I would like to end up with a navbar that looks like this:
我想最终得到一个如下所示的导航栏：
I'd like one row that has a left aligned column with the logo and a right aligned column with the user button and then a second row with center aligned buttons.
我想要一行带有徽标的左对齐列和带有用户按钮的右对齐列，然后是带有居中对齐按钮的第二行。
My thought was that I could create two divs with the class "col-lg-6 col-md-6", one for the logo and one for the User Button. These two would create the first 12 column row which would force the tags that follow onto a whole new row.
我的想法是我可以用类“col-lg-6 col-md-6”创建两个 div，一个用于徽标，另一个用于用户按钮。这两个将创建前 12 列的行，这将强制后面的标签进入一个全新的行。
When I try that, though, I end up with everything running inline and out of order.
但是，当我尝试这样做时，我最终发现所有内容都内联且无序运行。
I know I can do it by adding my own custom css (which is how I was able to mock up the first screen shot), but my preference would be to stick to using the bootstrap column system so my ad-hoc css doesn't f something up down the line. I would also like to understand what I did wrong (this is my first project using bootstrap so I'm still trying to get over the learning curve).
我知道我可以通过添加我自己的自定义 css（这是我能够模拟第一个屏幕截图的方式）来做到这一点，但我的偏好是坚持使用引导列系统，这样我的临时 css 就不会下线的东西。我还想了解我做错了什么（这是我使用引导程序的第一个项目，所以我仍在努力克服学习曲线）。
Here's my code for this demo page:

You just have to add following div element before following line where
您只需要在以下行之前添加以下 div 元素
<div class="collapse navbar-collapse" id="mainNav">
add following div element
添加以下 div 元素
<div class="clearfix"></div>
so final code looks similar to:
所以最终的代码看起来类似于：
<!-- SOME CODE -->
<div class="clearfix"></div>
<div class="collapse navbar-collapse" id="mainNav">
<!-- SOME CODE -->

Another approach is to use the nav-justifiedin a new row. Then you can eliminate the custom navbar CSS..
另一种方法是nav-justified在新的row. 然后你可以消除自定义导航栏 CSS..
<div class="row">
<div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1">
<div class="collapse navbar-collapse" id="mainNav">
<ul id="navlist" class="nav nav-justified">
<li><a href="#">Reports</a></li>
<li><a href="#">Account Management</a></li>
<li><a href="#">Messages</a></li>
<li><a href="#">Contact</a></li>
<li><a href="#">Request a Quote</a></li>
<li><a href="#">MainSite.com</a></li>
</ul>
</div>

You should not be trying to build a navbar by columns you define yourself but use the bootstrap native navbar which should do what you want it to and collapses really nicely into a menu button for smaller screens. Docs are here: https://getbootstrap.com/components/#navbar. Good Luck.
您不应该尝试通过您自己定义的列来构建导航栏，而是使用引导程序原生导航栏，它应该按照您的意愿行事，并且非常好地折叠成用于较小屏幕的菜单按钮。文档在这里：https: //getbootstrap.com/components/#navbar。祝你好运。
