纯css实现瀑布流(multi-column多列及flex布局)

瀑布流的布局自我感觉还是很吸引人的,最近又看到实现瀑布流这个做法,在这里记录下,特别的,感觉flex布局实现瀑布流还是有点懵的样子,不过现在就可以明白它的原理了  


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
/* html文件 */<!-- 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>
/* css样式 */body {    background: #e5e5e5;}/* 瀑布流最外层 */#root {     margin: 0 auto;     width: 1200px;     column-count: 5;     column-width: 240px;     column-gap: 20px;}/* 每一列图片包含层 */.item {     margin-bottom: 10px;     /* 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: avoid;     background: #fff;}.item:hover {     box-shadow: 2px 2px 2px rgba(0, 0, 0, .5);}/* 图片 */.itemImg {     width: 100%;     vertical-align: middle;}/* 图片下的信息包含层 */.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);}


2.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
/* html文件(只截取两列布局)*/<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>
/* css文件 */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
