Question

我有一个flexbox父级设置了flex-direction：row。在这个家长里面，我有两个孩子。我希望他们有相同的高度！

在这些孩子中，我有动态内容（可变高度）。

我正在做的方式，如果我在正确的孩子上添加文字，左边的一个会增长。但如果左孩子长大，那么右孩子就会变小。

他们不应该以同样的方式行事吗？

默认情况下，Flex项目与strech对齐。 height:100%课程中的.right值会阻止其占据整个高度，因此请尝试将height:100%移至.right元素

#main {
  width: 100%;
  height: auto;
  margin-top: 30px;
  display: flex;
  flex-direction: row;
  justify-content: space-between;
  align-items: stretch;
  background-color: red;
}

.left {
  width: 400px;
  display: flex;
  flex-direction: column;
  background: lime;
  align-items: stretch;
}

.title {
  width: 100%;
  font-size: 1.5em;
  color: #525252;
  display: flex;
  justify-content: center;
  margin-bottom: 20px;
  font-weight: bold;
  font-family: "emir-bold";
}

.left-area {
  width: 100%;
  display: flex;
  flex-direction: column;
}

.left-area-row {
  width: 100%;
  display: flex;
  flex-direction: row;
  justify-content: space-between;

.left-area-row-titulo {
  width: 49.5%;
  display: flex;
