Bootstrap 4导航栏中的分隔符

Question

我正在尝试在 navbar 中的 nav-items 之间放置分隔符，但我不知道如何在 nav-item 之间均匀设置分隔符的填充。

我的第二个问题是，当导航栏折叠时，在 toggle-navbar 中出现了分隔符，我尝试去除它们，但没有成功。

如果有更好的方法来创建分隔符，我将不胜感激。

以下是我的代码：

.navbar-nav > li > a::after {
    content: "|";
    padding: 0 5px
}

<div class="collapse navbar-collapse" id="navbarResponsive">
  <!--
  1) collapse - class dedicate to a given alement
  2) navbar-collapse:  show elements to bootstrap which belong to navbar, then use function - collapse
  -->
  <ul class="navbar-nav ml-auto">
    <li class="nav-item active">
      <a class="nav-link" href="#">O nas</a>
    </li>
    <li class="nav-item active">
      <a class="nav-link" href="#">Cennik</a>
    </li>
    <li class="nav-item active">
      <a class="nav-link" href="#">Usługi</a>
    </li>
    <li class="nav-item active">
      <a class="nav-link" href="#">Rejestracja</a>
    </li>
    <li class="nav-item active">
      <a class="nav-link" href="#">Porady</a>
    </li>
  </ul>
</div>

你能提供一张你想要实现的图片吗？我不太明白你想做什么。 - mdubus

我刚刚在我的帖子中添加了图片链接。分隔符，我的意思是这些竖线。 - Mr. Daniel

Answer 1

也许在你的导航项上使用border-right CSS样式可以解决问题，并且您可以在特定的断点（下面的示例中选择了MD）上禁用它们。

.border-md-right {
  border-right: 1px solid silver;
}

@media (max-width: 768px) {

  .border-md-right {
    border-right: none;
  }

}

Answer 2

@Shidersz的解决方案应该可行。如果您不想在每个li中添加额外的类，还有另一种解决方案。但是，如果您有一个动态菜单，并且必须将此类添加到除最后一个元素之外的每个元素上，则可能会更加困难！

.navbar-nav .nav-item:not(:last-child) {
   border-right: 1px solid silver;
}

@media (max-width: 768px) {
  .navbar-nav .nav-item:not(:last-child) {
    border-right: none;
  }
}

Answer 3

我使用 Bootstrap 4 成功地运行了这个。

.navbar-nav > li > a::after {
    content:'|';
    padding-left:10px;
    @media (max-width: 767px) {
        content: none;
        padding-left:0;
    }
}
 .navbar-nav > li:last-child > a::after {
         content:none;
}

不错的解决方案，使用了 last-child。但是格式有点问题，第一行也没有显示出来，所以我编辑了一下，将反引号移到了单独的一行。 - Tobias J

Answer 4

使用Bootstrap 5可以实现此功能

<nav class="navbar navbar-expand">
    <div class="collapse navbar-collapse" id="navbarNav">
        <ul class="navbar-nav">
            <li class="nav-item">
                <a class="nav-link" href="#">Home</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Features</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Pricing</a>
            </li>
            <li class="nav-item">
                <a class="nav-link">Disabled</a>
            </li>
        </ul>
    </div>
</nav>

还有CSS

.navbar-nav > li > a::after {
    content: '|';
    padding-left: 15px;
}

.navbar-nav > li:last-child > a::after {
    content: none;
}
