css - 是否可以用 css 创建不同的溢出子项？

Question

假设我有 div a，其中包含 n div元素 n..b,c;我想要那个div a 将为每个元素 ( overflow: scroll ) 获取滚动条，除了元素 c 应该是 overflow: visible .

我可以只使用 CSS 来实现吗？

为了让您更清楚，这就是我要实现的目标 https://jsfiddle.net/gm6cgyqp/除了 fixed 不响应滚动这一事实。我正在尝试使用引导下拉菜单实现与 native 选择相同的感觉，这就是我遇到此类问题的方式。

是的，这是可以做到的。将 max-height 和 max-width 设置为您想要滚动条的 div。

.wrap {
  width: 100%;
}
.a,
.b,
.c,
.d {
  max-width: 20%;
  overflow: scroll;
  display: inline-block;
  max-height: 100px;
}
.e {
  overflow: visible;
  width: 20%;
}

<div class="wrap">
