Answer 1

我想你正在寻找这样的东西，对吧？

您最好创建一个片段并重新创建您的问题，这样每个人都可以理解并帮助您解决问题。

问题是您设置了元素 position: absolute，所以它只是保持基于其 relative 父元素的位置。滚动不会移动它。

此示例将帮助您更好地理解仓位的运作方式https://codepen.io/AlHakem/pen/YayxBo

.scroller {
  max-height: 150px;
  overflow-y: scroll;
  height: 150px;
  float: left;
  width: 200px;
}

.item {
  position: relative;
}

.temp-description-popup {
  visibility: hidden;
  height: 0px;
}

.item:hover>.temp-description-popup {
  visibility: visible;
  height: auto;
  padding: 4px;
  background-color: #f1f1f1;
  border-radius: 4px;
  position: absolute;
  top: 25px;
  z-indeX: 2;
}
