简单的一行两列，用的-webkit-box-flex: 1
那么2列的宽度应该都是50%,可是实际情况是，文字多的那一列，宽度会更多一点。为什么呢？

Answer 1

Just add width: 0;, those who add -webkit-box-flex: 1;

Answer 2

-webkit-box-flex: 1 means that the ratio of allocating the remaining width of the parent container is 1:1, not the total width of the parent container. If you write more content on the second sub-element, the effect will be obvious:

<p class="bb">1122234411222344112223441122234411222344</p>
