純css實現瀑布流（multi-column多列及flex布局）

瀑布流的布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，在這里記錄下，特別的，感覺flex布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設置列數
• column-gap設置列與列之間的間距
• column-width設置每列的寬度

還要結合在子容器中設置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

/* html文件 */
<!-- 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">牽起你的左手護着你</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">牽起你的左手護着你</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">牽起你的左手護着你</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">牽起你的左手護着你</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布局實現瀑布流

• 將外層設置為row布局，然后再設置一個容器並設置為column布局，它是將列作為一個整體，然后在對列進行划分，在列里進行寬固定來實現的

/* 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">牽起你的左手護着你</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">牽起你的左手護着你</span>

    flex-direction: row;
    margin: 0 auto;

實踐后發現，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
