align-self：flex-end在flexbox中不起作用

Question

我正在使用＆＃34; milligram.css＆＃34; （a micro CSS framework）。

我想将列内的DIV对齐到底部。

但没有任何反应，DIV总是排在最前面。

https://jsfiddle.net/fb8ydfcy/3/

＆＃13;

＆＃13;

.column {
  border: 1px solid red;
}

.col-bottom {
  border: 3px solid blue;
}

Answer 1

您正在将flex属性应用于block元素的子元素。这些属性将被忽略，因为您位于block formatting context。

从display: block切换到display: flex以建立flex formatting context。

而不是：

.row .column {
  display: block;
  flex: 1;
  margin-left: 0;
  max-width: 100%;
  width: 100%;
}

试试这个：

.row .column {
  display: flex; /* adjusted */
  flex: 1;
  margin-left: 0;
  max-width: 100%;
  width: 100%;
}

有关align-self和其他十字轴对齐属性的说明，请参阅此处：

• How does flex-wrap work with align-self, align-items and align-content?

要了解沿着主轴的柔性对齐，请参见此处：

• In CSS Flexbox, why are there no "justify-items" and "justify-self" properties?
