Question

这是我的fiddle

我正在尝试制作100％高度的div，并且当该特定div中有更多内容时它应该是可滚动的。

我正在使用flex属性，但我的代码无法正常工作 - 当内容超过div高度时，它不会滚动。

body {
  font-family: 'arial';
}
header,
footer {
  background: #333;
  height: 30px;
  color: #fff;
}
img {
  width: 100%;
}
.wrapper {
  bottom: 0;
  display: flex;
  flex-direction: column;
  height: 100vh;
  overflow: hidden;
  position: relative;
  top: 0;
  width: 100%;
  background: #ccc;
}
.content {
  height: 100%;
  width: 100%;
  -webkit-box-flex: 2;
  /* OLD - iOS 6-, Safari 3.1-6 */
  -moz-box-flex: 2;
  /* OLD - Firefox 19- */
  -webkit-flex: 2;
  /* Chrome */
  -ms-flex: 2;
  /* IE 10 */
  flex: 2;
  /* NEW, Spec - Opera 12.1, Firefox 20+ */
}
.content .inner_content {
  display: table;
  width: 100%;
  height: 100%;
}
.content .inner_content .left_content {
  display: table-cell;
  background: yellow;
  width: 50%;
  padding: 10px;
}
.content .inner_content .right_content {
  display: table-cell;
  background: green;
  width: 60%;
  padding: 10px;
}
.scrollable-content {
  background: #ddd;
  padding: 10px;
}

Answer 1

我不确定这是否是您想要获得的效果，但请尝试添加＆＃39;溢出＆＃39;在div CSS定义中，例如：

.scrollable-content{
  background:#ddd;
  padding:10px;
  overflow: auto; max-height: 100%;
}

Here is a fiddle for you to play with

Answer 3

您需要设置可滚动容器的最大高度。

 max-height: 100%;

然后你必须说你想要垂直溢出是可滚动的：

overflow-y: scroll;

Answer 4

到目前为止，我正在考虑你的想法，我认为你正试图为你的div获得一个固定的高度，如果内容更多，你希望它们适合div。

您可以为div使用固定高度，也可以使用css overflow 属性来获取可滚动内容。

所以我认为您的解决方案可能如下 -

.scrollable-content{
    background:#ddd;
    padding:10px;
    height: (your desired height goes here);
    overflow:scroll;
}

我无法使div高度100％＆amp;在CSS中可滚动
