Flexbox定位IE11

Question

尽管我进行了所有研究，但我无法在IE11上使用flexbox修复网格的位置。其他浏览器没有问题，包括Edge。

我已经在caniuse上阅读了Flexbox的规格，但我仍然没有看到如何在不破坏其他浏览器设置的情况下解决我的问题。

一个想法？非常感谢你。

CSS：

* {
  box-sizing: border-box;
}

.steps {
  .steps-list {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
  }

  .step {
    align-items: center;
    display: flex;
    flex-direction: column;
    flex: 1 0 auto;
    padding: 20px;
    width: 25%;

    @media (max-width: 740px) {
      padding-bottom: 30px;
      width: 48%;
    }
  }

  .step__thumb {
    background-color: #f7f7f7;
    border-radius: 50%;
    color: red;
    font-size: 1.4rem;
    font-weight: 500;
    height: 110px;
    line-height: 110px;
    margin-bottom: 18px;
    width: 110px;
  }

  .step__text {
    color: lighten(#202124, 20%);
    font-size: 1.4rem;
    font-weight: 300;
    list-style: circle;
    text-align: left;
  }
}

将width: 100%添加到.step__text

我不完全确定为什么会这样，但我以前遇到过类似的问题，并且定义宽度似乎有效。
