为什么在行flexbox换行后内容溢出

Question

在下面的示例中，您能解释一下boxPurple在boxOrange下换行时boxOrange内容溢出的原因吗？

在这里找到了一些解决媒体查询或JS问题的方法

#container {
  background-color: red;
  padding: 10px;
  width: 80%;
  height: 300px;
  display: flex;
  flex-wrap: wrap;
  align-items: stretch;
}
#boxOrange {
  background-color: orange;
  flex: 1;
  overflow: scroll;
  min-width: 400px;
}
#boxPurple {
  background-color: purple;
  flex: 1;
  min-width: 400px;
}

<div id=container>
  <div id="boxOrange">

Answer 1

只要看一眼，就可以尝试为#boxOrange 设置最大高度

Answer 2

这就是您想要的吗？？

你必须给容器min-height:300;、boxOrange和boxPurple height:300px;，如果你放overflow: auto;，滚动条就只在旁边！

#container {
  background-color: red;
  padding: 10px;
  width: 80%;
  min-height: 300px;
  display: flex;
  flex-wrap: wrap;
  align-items: stretch;
}
#boxOrange {
  background-color: orange;
  flex: 1;
  overflow: auto;
  min-width: 400px;
 height:300px;
}
#boxPurple {
  background-color: purple;
  flex: 2;
  min-width: 400px;
  height:300px;
}

<div id=container>
  <div id="boxOrange">
