Question

我是新手。我在同一问题上浏览了很多帖子，尝试了许多不同的方法，但是没有运气。.我希望徽标在左侧，导航链接在右侧。到目前为止，我已经尝试了：

1。将ul（.navbar-nav）放置在具有flex方向的flex-container类的div中：row-reverse;

2。在ul（.navbar-nav）中添加mr-auto类

3。将ml-auto类添加到ul（.navbar-nav）

Answer 1

您需要在<ul class="navbar-nav mr-auto">上更改班级名称。

您必须将类mr-auto替换为ml-auto。

</nav>

我希望这能帮助您解决问题。

谢谢...

Answer 2

由于您的div（具有id = navbarNavDropdown）正在使用display flex，因此我添加了mr-auto以使项目向右对齐，并向内部ul元素删除了key，现在它可以正常工作了。

Answer 3

如果您想在左侧留一些间距并写入，只需更改以下填充值即可。否则，将其保持为0。您将必须添加以下CSS：-

.navber { padding: 0; }

然后您将不得不替换此行：-

<ul class="navbar-nav mr-auto">

使用：-

<ul class="navbar-nav ml-auto">

这将解决您的问题。
