我也想把每一个导航条项目放在更靠右的位置。我知道我可以用CSS来实现这个功能，但是我是否缺少一个Boostrap类？

你 ul 标签没有关闭，我修复了这个问题，并回答了你的 bonus 问题也是如此。

  1. 之所以在过文上，是因为，既。dropdown 和 link 在同一个区块内，所以你必须指定了 width 为了让这些人能够直插其中，我刚刚提供了 100px 在...之下 .nav-link{...} 你可以根据你的要求自由更改。
  2. 要将内容向右移动，你可以有 width 属性的黄色块(在我的snipppetfiddle中查看)，或者你可以为黄色块提供 flex 选项，并使用'justify-content:space-between;'。

在全屏中查看，由于 media-query 你用过的。

.nav-link{ border:1px solid yellow; margin:5px; width:100px; }

在你的代码中".dropdown-toggle::after "正确的值是问题，改成这个代码就可以了。

.dropdown-toggle::after {
    display: block;
    position: absolute;
    top: 50%;
    right: -7px;
    transform: translateY(-50%);
}

删掉下面你设计的手动CSS，因为它覆盖了bootstrap的默认CSS，这是不合适的。

.dropdown-toggle::after {
  display: block;
  position: absolute;
  top: 50%;
  right: 20px;
  transform: translateY(-50%);
}
