这篇文章主要介绍了纯css如何实现瀑布流，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
1.multi-column多列布局实现瀑布流
先简单的讲下multi-column相关的部分属性
column-count设置列数column-gap设置列与列之间的间距column-width设置每列的宽度
还要结合在子容器中设置break-inside防止多列布局，分页媒体和多区域上下文中的意外中断
break-inside属性值
auto 指定既不强制也不禁止元素内的页/列中断。
avoid 指定避免元素内的分页符。
avoid-page 指定避免元素内的分页符。
avoid-column 指定避免元素内的列中断。
avoid-region 指定避免元素内的区域中断。
截取了部分，可自己填充
<!-- 使用multi-columns实现瀑布流 --><div id="root"> <div class="item"> <img class="itemImg" src="../images/1.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/2.jpg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/3.jpg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/4.jpg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/5.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div></div>body { background: #e5e5e5;}#root { margin: 0 auto; width: 1200px; column-count: 5; column-width: 240px; column-gap: 20px;}.item { margin-bottom: 10px; break-inside: avoid; background: #fff;}.item:hover { box-shadow: 2px 2px 2px rgba(0, 0, 0, .5);}.itemImg { width: 100%; vertical-align: middle;}.userInfo { padding: 5px 10px;}.avatar { vertical-align: middle; width: 30px; height: 30px; border-radius: 50%;}.username { margin-left: 5px; text-shadow: 2px 2px 2px rgba(0, 0, 0, .3);}
flex布局实现瀑布流将外层设置为row布局，然后再设置一个容器并设置为column布局，它是将列作为一个整体，然后在对列进行划分，在列里进行宽固定来实现的
<div id="root"> <div class="itemContainer"> <div class="item"> <img class="itemImg" src="../images/1.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/2.jpg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/3.jpg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/4.jpg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/5.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/6.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/7.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> </div> <div class="itemContainer"> <div class="item"> <img class="itemImg" src="../images/5.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/7.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/6.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/5.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/6.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> <div class="item"> <img class="itemImg" src="../images/6.jpeg" alt=""/> <div class="userInfo"> <img class="avatar" src="../images/gift.png" alt=""/> <span class="username">牵起你的左手护着你</span> </div> </div> </div></div>body{ background: #e5e5e5;}#root{ display: flex; flex-direction: row; margin: 0 auto; width: 1200px;}.itemContainer{ margin-right: 10px; flex-direction: column; width: 240px;}.item{ margin-bottom: 10px; background: #fff;}.itemImg{ width: 100%;}.userInfo { padding: 5px 10px;}.avatar { vertical-align: middle; width: 30px; height: 30px; border-radius: 50%;}.username { margin-left: 5px; text-shadow: 2px 2px 2px rgba(0, 0, 0, .3);}
实践后发现，纯css实现的瀑布流只能是一列一列的排布，所以还是得用js来实现瀑布流更符合我们常见的瀑布流
