如何通过下面的导航链接将Boostrap 4中的导航栏徽标居中 [英] How to centre navbar logo in Boostrap 4 with nav-links below

问题描述

我似乎无法使导航栏徽标与它下面的导航链接中心居中对齐.我确定我缺少一些简单的东西，我已经查看了有关此问题的其他几篇文章，但是似乎所有文章都在使用旧版的bootstrap.我目前正在使用Bootstrap 4.0.

I can't seem to get the navbar logo to centre align with the nav-links centre below it. I'm sure I'm missing something simple, I've checked out a few other posts regarding this issue but all seem to be using older versions of bootstrap. I am currently using bootstrap 4.0.

具体地说，我希望徽标位于其自己的单独行中，而不是与链接位于同一行中.

Specifically, I want the logo on its own separate row, not on the same one as the links.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#"><img src="img/h-tech-logo-cropped.png"/></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
  <span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
  <ul class="navbar-nav">
    <li class="nav-item">
      <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Our Services</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">About Us</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Gallery</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Contact Us</a>
    </li>
  </ul>
</div>

推荐答案

这是使用 flexbox 和 auto-margin 实用程序的问题，如许多其他"Bootstrap 4 Navbar Center"问题...

It's a matter of using the flexbox and auto-margin utils as explained in the many other "Bootstrap 4 Navbar Center" questions...

• 导航栏为display:flex，因此请使用flex-column创建内容堆栈
• 使用mx-auto可使自动x轴边距居中.

• The navbar is display:flex so use flex-column to make content stack
• Use mx-auto for auto x-axis margins to center.
