CSS实现瀑布流的两种方式
瀑布流又称瀑布流式布局，是比较流行的一种网站页面布局方式。在手机端进行多图片展示时会经常用到。即多行等宽元素排列，后面的元素依次添加到其后，等宽不等高，根据图片原比例缩放直至宽度达到我们的要求，依次按照规则放入指定位置。
那么瀑布流式布局有哪些实现方式呢？
column 多行布局实现瀑布流
column实现瀑布流主要依赖两个属性。
column-count属性，是控制屏幕分为多少列。
column-gap属性，是控制列与列之间的距离。

flex 弹性布局实现瀑布流
flex实现瀑布流需要将最外层元素设置为display: flex，使用弹性布局
flex-flow:column wrap使其纵向排列并且换行换行设置
height: 100vh填充屏幕的高度，也可以设置为单位为px的高度，来容纳子元素。每一列的宽度可用
calc函数来设置，即width: calc(100%/3 - 20px)。分成等宽的3列减掉左右两遍的margin距离。
