html - 悬停效果未覆盖分配类的所有 div
问题描述
我有一个使用（短）视频作为菜单选项的汉堡切换菜单。css 代码是通过 sass 编写的，因此我将同时包含 scss 和相应的 css 代码。
所有这些菜单选项都应该具有功能链接和悬停效果，以悬停效果移除黑色#000 覆盖，将覆盖 div 的不透明度设置为 0。
但是，只有第一个 (1/4) 和最后一个 (4/4) 菜单选项具有悬停效果和功能链接。链接无处可去，但指针光标显示在这两个 .footer-content div 上。
我已经尝试将第二个和第三个 .footer-content HTML div 重写为，除了内容之外，与正常运行的第一个和第四个 div 的代码相同。我还尝试将类拆分为 .footer-content-1 直到四个，没有任何改变。
这是html代码，我试图在评论中进行描述。请原谅我发布整个代码，我只是不确定哪些细节会导致问题：

解决方案
这是因为您的主容器用z-index: 1;.
尝试从中删除z-index，你会没事的：
#showcase .showcase-container {
z-index: 1;
}
