javascript - 左右顶部导航栏菜单，调整大小时重叠

Question

我使用的是 Bootstrap 3，并且有一个固定的标题导航栏。我的左边有几个菜单项，右边有三个。类似于 Stackoverflow 的方式(减去搜索栏)。

当我缩小浏览器窗口时 - 右侧菜单项位于左侧菜单项下方，直到它最终提供切换开关。

如何解决此问题，使其不会将右侧菜单项移动到左侧元素下方？

 body {
      min-height: 70px;
      padding-top: 70px;
    }

Answer 1

您需要使用媒体查询..因为您有许多菜单项，您需要根据屏幕尺寸更改字体大小和边距。

我提供了一种只改变字体大小的解决方案 您可以修改很多参数来优化字体大小填充和所有内容。

 body {
      min-height: 70px;
      padding-top: 70px;
    }
@media (min-width: 767px) and (max-width: 1200px)  {
    .navbar-nav > li > a {
    font-size:8px;
    padding-left: 5px;
    padding-right: 5px;
   
    }
    .navbar-brand {
      font-size: 15px;
    }
}
