在Bootstrap中，创建Logo a在左边、菜单项在中间、Logo B在右边的导航栏的最平台友好的方法是什么?
这是我迄今为止尝试过的，它最终被对齐，使标志A在左边，菜单项旁边的标志在左边，标志B在右边。
<div class="navbar navbar-fixed-top navbar-custom ">
<div class="container" >
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"><span class="navbar-logo">Logo_A</span></a>
</div>
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="#about">Menu Item 1</a></li>
<li><a href="#contact">Menu Item 2</a></li>
<li><a href="#about">Menu Item 3</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="#"><img src="images/Logo_B.png" class="img-responsive"></a></li>
</ul>
</div>

在Zim的回答中，例子5的左边和中间只有空白的右边并不是真正的中心navlinks。我们可以用一些改变来修复它:

Bootstrap不允许我们设置flex-basis:0，所以属性仍然是自动的，间隔器不会相等地展开。所以导航链接不是居中。
我们可以在brand container上使用class position-absolute，在navlinks上使用mx-auto w-100。切换器将导航条的最小高度设置为2.5rem。我们必须设置为流体div容器。

我们有很多方法来对齐导航栏项目。
左对齐
Class = "navbar-nav mr-auto"
右对齐
Class = "navbar-nav ml-auto"
对于中心对齐
Class = "navbar-nav mx-auto"
<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
<a routerLink="/" class="navbar-brand" href="#">Bootstrap 4</a>
<ul class="navbar-nav ml-auto">
<li class="nav-item">
<a class="nav-link" href="home">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="about">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="contact">Contact us</a>
</li>
</ul>
</nav>
