Flexbox定位IE11 [重复]

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。在其他浏览器上没有问题，包括Edge。

我已经阅读了 caniuse 上 Flexbox 的规范，但我仍然不知道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。

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，但我之前遇到过类似的问题，定义宽度似乎可行。
