css – Flexbox子句溢出父级,在IE上指定了max-height

我有一个父元素,包含两个子元素,使用flexbox显示在彼此之上.此父元素的max-height属性设置为特定值.因此,只要内容很短,父元素应该保持较小,随着内容的增长,父元素随之增长,直到满足其最大高度.此时我们应该在内容元素上看到滚动条.

#container {
  display: flex;
  max-width: 80vw;
  max-height: 100px;
  flex-direction: column;
}

#content {
  overflow-y: auto;
}

/* styling - ignore */
#container {
  border: 2px solid black;
  margin-bottom: 1em;
}
#header {
  BACkground-color: rgb(245,245,245);
  padding: 10px;
}
#content {
  BACkground-color: rgb(255,255,255);
  padding: 0 10px;
}

<div id="container">
  <div id="header">Header</div>
  <div id="content">
    <p>Everything works as supposed to,move along</p>
  </div>
</div>

<div id="container">
  <div id="header">Header</div>
  <div id="content">
    <p>Very long content</p>
    <p>Very long content</p>
    <p>Very long content</p>
    <p>Very long content</p>
  </div>
</div>

这适用于Firefox和Chrome.在Internet Explorer上,虽然未显示内容元素中的滚动条;相反,内容元素从父元素溢出.

我试着玩flex-basis和其他flexbox属性,google了很多,但没有任何运气.

#container {
  display: flex;
  max-width: 80vw;
  height: 100px;
  flex-direction: column;
}

#container {
  display: flex;
  max-width: 80vw;
  height: 100px;
  flex-direction: column;
}

#content {
  overflow-y: auto;
}

/* styling - ignore */
#container {
  border: 2px solid black;
  margin-bottom: 1em;
}
#header {
  BACkground-color: rgb(245,move along</p>
  </div>
</div>

<div id="container">
  <div id="header">Header</div>
  <div id="content">
    <p>Very long content</p>
    <p>Very long content</p>
    <p>Very long content</p>
    <p>Very long content</p>
  </div>
</div>
