瀑布流的布局自我感覺還是很吸引人的，最近又看到實現(xiàn)瀑布流這個做法，在這里記錄下，特別的，感覺flex布局實現(xiàn)瀑布流還是有點懵的樣子，不過現(xiàn)在就可以明白它的原理了
1.multi-column多列布局實現(xiàn)瀑布流
先簡單的講下multi-column相關(guān)的部分屬性
column-count設(shè)置列數(shù)column-gap設(shè)置列與列之間的間距column-width設(shè)置每列的寬度
還要結(jié)合在子容器中設(shè)置break-inside防止多列布局，分頁媒體和多區(qū)域上下文中的意外中斷
break-inside屬性值
截取了部分，可自己填充
/* html文件 */<!-- 使用multi-columns實現(xiàn)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; /* 防止多列布局，分頁媒體和多區(qū)域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;}/* 圖片下的信息包含層 */.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(xiàn)瀑布流將外層設(shè)置為row布局，然后再設(shè)置一個容器并設(shè)置為column布局，它是將列作為一個整體，然后在對列進行劃分，在列里進行寬固定來實現(xiàn)的
/* html文件（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);}
實踐后發(fā)現(xiàn)，純css實現(xiàn)的瀑布流只能是一列一列的排布，所以還是得用js來實現(xiàn)瀑布流更符合我們常見的瀑布流
