css怎么实现瀑布流布局
css实现瀑布流布局的方法:1、利用multi-column多列布局实现。2、利用flex布局实现;只需将外层设置为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,在列里进行宽固定即可。
本教程操作环境:windows7系统、CSS3&&HTML5版、Dell G3电脑。
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
