当包装物品时，flexbox为什么不将后续内容压低？

Question

在for collectors div换行之前，我的布局可以正常工作。此时，后续的what artists are saying div不会被推送到包装内容的下方。有人知道为什么吗？

我尝试将“收藏家”弹性框的align-content设置为各种设置。

P.S。使用Tailwind.css

在元素未包装时显示

Answer 1

在父元素上设置绝对高度，然后在子元素上设置百分比高度时，会出现问题。一开始，我还不知道其他导致问题的测量组合。

Problem和 Solution

简化问题

<div class="parent">
  <div class="child-1">child 1</div>
  <div class="child-2">child 2</div>
</div>

<div class="other">Other div</div>

-

.parent {
  display: flex;
  flex-wrap: wrap;
  height: 80px;
}

.parent > div {
  flex: 1 1 50%;
  min-width: 300px;
  height: 100%; /* this is the problem */
}

.child-1 {
  background-color: red;
}

.child-2 {
  background-color: green;
}

.other {
  width: 100px;
  height: 100px;
  background-color: orange;
}

解决方案

/* removed parent height */
.parent {
  display: flex;
  flex-wrap: wrap;
}

.parent > div {
  flex: 1 1 50%;
  min-width: 300px;
  height: 50px; /* set an absolute height here */
}
