IE 11:图像在flexbox中无法正确缩小

Question

我正在尝试使用flexbox将两个图像放在一列中.在这种情况下,widthdiv容器的小于width图像的容器.在Chrome中,图像完全适合div容器,但它不在IE中,我不知道为什么.

div.outer {
  width: 400px;
  display: flex;
  flex-direction: column;
  justify-content: space-around;
}

div.inner {
  width: 100%;
  border: 1px solid red;
}

img {
  width: 100%;
  height: auto;
}

<div class="outer">
  <div class="inner">
    <img src="http://placehold.it/480x360">
  </div>

  <div class="inner">
    <img src="http://placehold.it/480x360">
  </div>
</div>

这就是我在IE 11中得到的:

Answer 1

IE11似乎在flex-shrink属性的初始值上有些麻烦.如果将其设置为零(最初设置为1),它应该工作:

div.outer {
  width: 400px;
  display: flex;
  flex-direction: column;
  justify-content: space-around;
}
div.inner {
  flex-shrink: 0;
  width: 100%;
  border: 1px solid red;
}
img {
  width: 100%;
  height: auto;
}

<div class="outer">
  <div class="inner">
    <img src="http://placehold.it/480x360">
  </div>

  <div class="inner">
    <img src="http://placehold.it/480x360">
  </div>
</div>
