CSS怎么实现瀑布流？下面本篇文章给大家介绍一下使用CSS实现瀑布流的两种方式，希望对大家有所帮助！
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。
<!DOCTYPE html>
<html lang="en"><head>
<meta charset="UTF-8">

<style>
.box {
margin: 10px;
column-count: 3;
column-gap: 10px;
}
.item {
margin-bottom: 10px;
}
.item img{
width: 100%;
height:100%;
}
</style>
</head>

<div class="box">

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。
<!DOCTYPE html>

<meta charset="UTF-8">

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.box {
display: flex;
flex-flow: column wrap;
height: 100vh;
}
.item {
margin: 10px;
width: calc(100%/3 - 20px);
}
.item img{
width: 100%;
height:100%;
}
</style>
</head>
<body>
<div class="box">
