      <div>Lorem ipsum dolor sit amet consectetur adipiscing elit risus conubia ante, congue faucibus ac a non aptent nisi per commodo facilisi id, tempus lacus maecenas tincidunt mus sociosqu elementum ornare eget.

现在这个 HTML 是这样的错误

但我想要的是让Lorem ipsum文本溢出：滚动保持COL2的高度等于COL1像这样

如果Lorem Ipsum文本太短而不会溢出，那么它就会像这样克服自己

将广告保持在底部，因为Lorem Ipsum可以达到的最大高度。

在没有JS的情况下使用Bootstrap或CSS是否可行？

PS COL1没有/不能有Fixed-Height。

Answer 1

添加position:absolute到您的 COL2 的所有子项，这样它就不会影响 COL2 的高度。

.col-6 h1 {
  color: white;
  text-align: center;
}

h1 {
  background-color: red;
  position: absolute;
  left: 0;
  right: 0;
  height: 50px;
  margin: 0 !important;
}

.COL1,
.COL2 {
  border: 1px solid red;
}

.COL2 .top-banner {
  top: 0;
}

.COL2 .bottom-banner {
  bottom: 0;
}

.COL2 div {
  position: absolute;
  top: 50px;
  left: 0;
  bottom: 50px;
  right: 0;
  overflow: auto;
}
