在IE11中Flex容器溢出容器

Question

我的flex容器有一个水平的项目列表,所有浏览器都在它们的父项中正确显示,除了IE11,它似乎无法将它们保留在其中,而是它们"流出"它,如下所示:

下面是我的设置的简化小提琴,它演示了操作中的问题:

ul, li {
  list-style: none;
  margin: 0;
  padding: 0;
}

ul {
  display: flex;
  width: 200px;
  border: 1px dashed red;
}

li img {
  max-width: 100%;
  height: auto;
}

<ul>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
</ul>

IE11上的结果:

任何解决方法？

Answer 1

看起来IE11要求您定义flex items(li)的大小:

ul, li {
  list-style: none;
  margin: 0;
  padding: 0;
}

ul {
  display: flex;
  width: 200px;
  border: 1px dashed red;
}
 
li {              /* NEW */
  flex: 0 1 100%; /* flex-grow, flex-shrink, flex-basis */
  /* flex: 1 */   /* alternatively, this also works (short for: fg:1, fs:1, fb:0px) */
}

li img {
  max-width: 100%;
  height: auto;
}

<ul>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
  <li><img src="http://i.imgur.com/60PVLis.png" width="50" height="50" alt=""></li>
</ul>
