純css實現瀑布流（multi-column多列及flex佈局）
阿新 • • 發佈：2020-07-16
瀑布流的佈局自我感覺還是很吸引人的，最近又看到實現瀑布流這個做法，在這裡記錄下，特別的，感覺flex佈局實現瀑布流還是有點懵的樣子，不過現在就可以明白它的原理了
1.multi-column多列布局實現瀑布流
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防止多列布局，分頁媒體和多區域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 指定避免元素內的區域中斷。 - 截取了部分，可自己填充

<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>

/* 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佈局實現瀑布流
- 將外層設定為row佈局，然後再設定一個容器並設定為column佈局，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

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
