Question

我一直试图让我的ul中的导航项正确浮动。我尝试了很多不同的东西，包括这个彻底答案中的所有内容： Bootstrap 4 align navbar item to the right

导航项目仍然卡在左侧。

在这一点上，我觉得我错过了一些明显的东西？包含列表项的div类是新添加的，并且就我所知的情况而言似乎对列表项的行为没有任何影响。我尝试过的所有东西都没有这些div标签，仅供参考。

好奇是否有人能在这里看到问题？

    .navbar-default {
      background-color: white;
    }
    
    .navbar {
      display: flex;
      min-height: 50px;
      border-bottom: 1px solid black;
      align-items: center;
      margin-bottom: 0;
    }
    
    
    .profile-dropdown {
      border-radius: 50%;
      height: 50px;
      width: 50px;
      border: 1px solid black;
      object-fit: cover;
    }

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    
      <a class="navbar-brand" href="#">Equilibrium</a>
    <!-- If the user is logged in, display a profile icon. -->
    
      <ul class="nav navbar-nav mr-auto">
    
     
          <li class="nav-item">
            <a>
              <img src="" class="profile-dropdown" alt="">
            </a>
          </li>
      
          <li class="nav-item" >
            <img src="/assets/glyphicons/user.png" class="profile-dropdown" alt="">
          </li>
   
    
      </ul>
    
    </nav>

我感谢任何帮助。感谢。

我在这里发布了Bootstrap 4工作导航栏的示例。这应该指向正确的方向。如果您还有任何疑问，请在评论中提问。

正如您所看到的，mr-auto类完美地运行在这里。它将右侧的内容推送到另一侧。（mr-auto =＆＃34; margin-right：auto＆＃34;）

这是工作代码：

Answer 2

您的问题是要将项目对齐。为此，您必须添加ml-auto而不是mr-auto。它会使所有项目保持正确对齐。

Bootstrap Nav项目不会向右浮动
