使 child 可滚动，同时保持 parents 填充

Question

我想让 child div (.content) 在超过其 parents 高度时可以滚动。我遇到的问题是维护它的 parents padding（.box padding），这样 .content 的文本就不会被放置就在底部边缘。

.box高度不固定为250px，仅供演示。

Fiddle

HTML

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

 </div>
</div>

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

就用这个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

尝试为您的内容区域框添加高度，而不是为您的父框分配一个高度，这样可以保持您想要的填充。

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

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