Question

我希望将子div（ .content ）设为可滚动，如果它超出其父级高度。我遇到的问题是维护其父级填充（ .box 填充），因此 .content 的文本不会放在底部边缘。

.box 高度未固定为250px，仅用于演示目的。

HTML

<div class="box">
 <h3>Title</h3>
 <div class="content">
  <p>

CSS

.box {
  width: 250px;
  height: 250px; //height is not fixed, just for demonstration purposes.
  padding: 25px;      
  overflow: hidden;

  background-color: rgb(200,200,200);
}

.content {
  overflow: scroll;
}

Answer 1

只需使用此CSS：

.box {
  display:flex;
  flex-flow: column;
  width: 250px;
  height: 250px;
  padding: 25px;
  overflow: hidden;
  background-color: rgb(200,200,200);
}

.content {
  flex:2;
  height:100%;
  width:100%;
  overflow-y: scroll;//only for y axis
}

Answer 2

尝试为内容区域框添加高度，而不是为父框指定高度，以保持所需的填充。

.box {
  width: 250px;
  padding: 25px;
  background-color: rgb(200,200,200);
}

.content {
  height: 250px;
  overflow: auto; 
}
