css - 标题悬停后如何制作无序列表 "stay"？

Question

在附带的笔中，我想编写我的代码，以便一旦用户将“选择设计”悬停在上方，选项就会保留，不会在用户将鼠标移开后立即消失。

这是我尝试过的:

nav[role=navigation] {
    display:none;
}

.select:hover + nav[role=navigation] {
    display:block;
}

P.S:我不允许更改 HTML。HTML 实际上是 CSS Zen Garden 的默认设计的一部分。

Answer 1

我添加了一个父 div 并给它上课。

nav[role=navigation] {
  display:none;
}

.select:hover nav[role=navigation] {
  display:block;
}
