如何在图像幻灯片放映上覆盖导航栏/汉堡

时间：2021-06-22 21:21:26

标签： javascript html css

我有一个带有响应式导航栏的主页。当您缩小窗口大小时，它会折叠成一个适用于移动设备/平板电脑的汉堡，然后在页面右侧垂直向下显示菜单选项。

主页还有一个自动运行的图片幻灯片，位于页面中央。

当窗口大小减小到移动设备大小并折叠成汉堡时，我在图片幻灯片上看不到某些菜单选项。关于如何实现这一点的任何想法？我是 HTML、CSS 和 JS 的新手……非常感谢任何帮助（：

您可以在 CSS 中使用 Z-index 来叠加元素。

示例：

nav{
 z-index: 1000;
}
