防止 Bootstrap 导航栏中的某些项目折叠 [重复]答案

【问题标题】：Keep some items in Bootstrap navbar from collapsing [duplicate]防止 Bootstrap 导航栏中的某些项目折叠 [重复]
【发布时间】：2018-03-22 15:37:00
【问题描述】：

我正在尝试创建一个 Bootstrap 导航栏，左侧是导航项目，右侧是社交/联系人图标。我希望导航项目折叠，但社交/联系人项目不要折叠。移动用户应该可以点击它们。

我查看了一些类似问题的答案，但不幸的是，Bootstrap v4 不向后兼容，并且解决方案不再有效。

我的代码看起来很简单。如果我将社交/联系人项目放在他们自己的 div 中，在折叠 div 之外，它们的布局很有趣。但是，如果我将它们放入折叠 div 中，它们会很好地排列。但是，它们崩溃了，这是我不想要的。我试着弄乱了一些弹性参数，但这似乎只会让事情变得更糟。

在理想的世界中，在移动视图中，我只有社交/联系人图标和右侧的汉堡菜单按钮。

#phone-number {
  padding: 0 1em;
  font-weight: bold;
}

.navbar-right {
  flex-direction: row;
}

@media (max-width: 767px) {
  #phone-number {
    display: none;
  }
}
