IE 11 Flexbox子溢出容器[重复]

Question

我整理了以下示例。它适用于所有主流浏览器，但不适用于 IE11。内容 div 溢出 flex 容器（没有滚动条）并向下推页脚。有什么建议？

html,
body {
  padding: 0;
  margin: 0;
}

.c1 {
  border: 1px solid blue;
  display: flex;
  flex-direction: column;
  max-width: 500px;
  max-height: 100px;
}

.h,
.f {
  flex: 0 0 auto;
}

.b {
  border: 1px solid red;
  flex: 1 1 auto;
  overflow: auto;
}

<div class="c1">
  <header class="h">header</header>
  <div class="b">What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type
    specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently
    with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

  </div>
  <footer class="f">footer</footer>
</div>

Answer 1

尝试将 c1 类中的 ma​​x-height 属性替换为 height 将有助于解决问题。

.c1 {
      border: 1px solid blue;
      display: flex;
      flex-direction: column;
      max-width: 500px;
      height: 100px;
    }

IE 11 中的输出：
