如何在 bootstrap 4 中将 nav-link 向右移动？

Question

请问如何将nav-link向右移动？因为我像 float: right 或 margin left:auto 一样尝试它，它会将汉堡菜单引导到中间。我希望汉堡菜单和导航 link 都在右侧。此外，当我将屏幕最小化时，汉堡包菜单和 navlink 都在右侧，当我将屏幕最小化时，nav-link 位于左侧。此外，当我将屏幕最小化时，我单击下拉菜单，导航栏变大，下拉菜单位于导航栏内，导致导航栏变大。我想要导航栏外的下拉菜单。我尝试使用 position: fixed、position :relative 和 position absolute，但都没有解决。所以想请教一下有没有什么解决办法。所以，我可以修复它。谢谢。

下面是我的代码：

Answer 1

为了将用户图标固定在右侧，我添加了这个 css:

a.nav-link.dropdown-toggle{
  text-align: right;
}

然后在大屏幕上，为了让您的 ul 始终位于右侧，我添加了 BS4 class ml-lg-auto，这将在 lg 断点上方的屏幕左侧添加边距 au。

要使汉堡包右对齐，请将 class ml-left 添加到您的按钮。

如果你想在小屏幕和大屏幕上获得相同的下拉效果，我添加了 css 如下：

@media (max-width: 991px){
  .user-dropdown-menu{
    position: absolute !important;
    left: -6rem !important;
  }
}

a.nav-link.dropdown-toggle{
  text-align: right;
}

@media (max-width: 991px){
  .user-dropdown-menu{
    position: absolute !important;
    left: -6rem !important;
  }
}
