左右顶部导航栏菜单，调整大小时重叠

Question

我正在使用Bootstrap 3，并且有一个固定的标题导航栏。我在左边有几个菜单项，右边有三个菜单项。类似于Stackoverflow(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项下方？

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

Answer 1

您需要使用媒体查询。由于您有许多菜单项，因此您需要根据屏幕大小更改字体大小和边距。

我提供了一个仅更改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。

示例代码段

 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;
    }
}
