效果如下：
三、flex 弹性布局实现瀑布流
思路分析：
flex 实现瀑布流需要将最外层元素设置为 display: flex，即横向排列。然后通过设置 flex-flow:column wrap 使其换行。设置 height: 100vh 填充屏幕的高度，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。
代码实现：
<!DOCTYPE html>
<html>
<head>
<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">
<div class="item">
<img src="banner.jpg" alt="" />
</div>
<div class="item">
<img src="show.jpg" alt="" />
</div>
<div class="item">
<img src="cloth.jpg" alt="" />
</div>
<div class="item">
<img src="banner.jpg" alt="" />
</div>
<div class="item">
<img src="show.jpg" alt="" />
</div>
<div class="item">
<img src="cloth.jpg" alt="" />
</div>
<div class="item">
<img src="banner.jpg" alt="" />
</div>
<div class="item">
<img src="show.jpg" alt="" />
</div>
<div class="item">
<img src="cloth.jpg" alt="" />
</div>
<div class="item">
<img src="show.jpg" alt="" />
