Flex布局
- 块级布局侧重垂直方向、行内布局侧重水平方向，flex布局是跟方向无关的
- flex布局可以实现空间自动分配、自动对齐(flexible:弹性布局);
- flex适用于简单的线性布局，更复杂的布局要交给Grid,这篇文章写的挺好，学到不少。
常用flex属性
- flex container(容器)属性？
flex-direaction:方向
flex-wrap:换行
flex-flow:上面另个的简写
justify-content:主轴方向对齐方式
align-items:侧轴对齐方式
align-content:多行/列内容对齐方式(用的少) - flex item属性？
flex-grow:增长比例(空间过多时)
flex-shrink:收缩比例(空间不够时)
flex-basis:默认大小（一般不用）
order:顺序（代替双飞翼）
align-self:自身对齐方式
align-content:多行/列内容对齐方式(用的少)
结合学习内容写个骰子布局
