純css如何?瀑布流？css實現瀑布流的兩種方式

瀑布流的布局感覺還是蠻不錯的，所以本篇文章就給大家來分享一下css實現瀑布流的兩種方法，通過multi-column多欄版面配置實現瀑布流和flex布局實現瀑布流。

1.multi-column多欄版面配置實現瀑布流

先簡單的講下multi-column相關的部分屬性

• column-count設定列數

• column-gap設定列與列之間的間距

• column-width設定每列的寬度

還要結合在子容器中設定break-inside防止多欄版面配置，分頁媒體和多地區上下文中的意外中斷

break-inside屬性值  auto  指定既不強制也不禁止元素內的頁/列中斷。  avoid  指定避免元素內的分頁符。  avoid-page  指定避免元素內的分頁符。  avoid-column 指定避免元素內的列中斷。  avoid-region  指定避免元素內的地區中斷。

• 截取了部分，可自己填充

/* html檔案 */<!-- 使用multi-columns實現瀑布流 --><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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</span>        </div>    </div></div>

/* css樣式 */body {    background: #e5e5e5;}/* 瀑布流最外層 */#root {     margin: 0 auto;     width: 1200px;     column-count: 5;     column-width: 240px;     column-gap: 20px;}/* 每一列圖片包含層 */.item {     margin-bottom: 10px;     /* 防止多欄版面配置，分頁媒體和多地區上下文中的意外中斷 */     break-inside: avoid;     background: #fff;}.item:hover {     box-shadow: 2px 2px 2px rgba(0, 0, 0, .5);}/* 圖片 */.itemImg {     width: 100%;     vertical-align: middle;}/* 圖片下的資訊包含層 */.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布局實現瀑布流

• 將外層設定為row布局，然後再設定一個容器並設定為column布局，它是將列作為一個整體，然後在對列進行劃分，在列裡進行寬固定來實現的

/* html檔案（只截取兩列布局）*/<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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</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">牽起你的左手護著你</span>            </div>        </div>    </div></div>

/* css檔案 */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);}

實踐後發現，純css實現的瀑布流只能是一列一列的排布，所以還是得用js來實現瀑布流更符合我們常見的瀑布流
