html - 两个DIV在同一个地方

Question

我的“搜索框和社交图标”隐藏在我的主菜单后面。这可能是因为我的 .hide-menu 类。我有一个 jQuery 插件，它使主菜单在向上滚动时出现，在向下滚动时消失。 我想要实现的是“搜索框和社交图标”DIV 始终显示在主菜单下方。这可能吗？

Answer 1

最简单的可能是在 .site_header 和 #search-social 之间使用同级选择器。确保 #search-social 已定位。像这样的东西:

#search-social {
  margin-bottom: 20px;
  position: relative;
}

header.site_header ~ #search-social {
  top: 40px;
}
header.site_header.hide-menu ~ #search-social {
  top: 0px;
}

注意:顶部样式需要根据菜单高度进行一些调整。
