如何使我的导航栏项目响应地在屏幕上伸展

Question

我想让我的导航栏中的项目在屏幕的宽度上伸展时，让我们说一台笔记本电脑，然后在手机上一个接一个。

另外，我不喜欢我的物品如何被推到左边，我希望它们在屏幕上的间距相等。

Answer 1

如果我理解正确，您应该做一些更改：

1. 阅读我添加的CSS。 我正在使用flex在菜单中平均拉伸项目。
2. 删除.container div以将导航拉伸到窗口的宽度。
3. 从您不需要的导航中删除.navbar-right类。

我没有关心移动设备我确定你知道如何只使用媒体查询在桌面上进行所有这些更改。

 .navbar-brand, .navbar-nav, .navbar-nav>li { float:none !important; } .navbar-nav { display:flex; } .navbar-nav>li { flex: 1; }

Answer 2

您必须使用媒体查询才能获得响应式视图。

.navbar-brand{
  width:100%;
  display:inline-block;
}
.navbar-brand ul li{
  width:20%; 
  /*Adjust the percent based on 100/number of items (Here it is 5)*/
  min-width:150px;
  /*Keep a minimum width such that the text does not overflow*/
  display:inline-block;
  text-align:center;
}

/*Write media queries for Mobile and tablets*/
@media (max-width: 420px) {
  .navbar-brand ul li{
     width:100%;
   }
}
