html - CSS 列数 - 更改顺序

Question

我想在这里更改列的顺序:

#container {
    position: relative;
    width: 600px;
}

#column-wrapper {
    -webkit-column-count: 3;
    -moz-column-count: 3;
    column-count: 3;
    -webkit-column-gap: 20px; 
    -moz-column-gap: 20px;
    column-gap: 20px;
}

#column-wrapper .column {
    display: inline-block;
    width: 100%;
    padding: 20px 0;
    margin-bottom: 20px;
    background-color: green;
    text-align: center;
    font-size: 20px;
    font-weight: bold;
    color: #fff;
}

<div id="container">

    <div id="column-wrapper">
        
        <div class="column">
            <span>1</span>
        </div>
        
        <div class="column">
            <span>2</span>
        </div>
        
        <div class="column">
            <span>3</span>
        </div>
        
        <div class="column">
            <span>4</span>
        </div>
        
         <div class="column">
            <span>5</span>
        </div>
        
         <div class="column">
            <span>6</span>
        </div>
        
    </div>
    
</div>

结果应该是这样的:

有人知道一个简单的解决方案吗？

Answer 1

当您想要基于行的顺序时为什么要使用列？看起来像是 the flex model 的工作.在不更改 HTML 的情况下，您可以这样做:

#container {
    position: relative;
    width: 600px;
}

#column-wrapper {
    display: flex;
    flex-wrap: wrap
}

#column-wrapper .column {
    display: inline-block;
    width: calc(30% - 20px);
    padding: 20px 0;
    margin: 20px;
    background-color: green;
    text-align: center;
    font-size: 20px;
    font-weight: bold;
    color: #fff;
}

<div id="container">

    <div id="column-wrapper">
        
        <div class="column">
            <span>1</span>
        </div>
        
        <div class="column">
            <span>2</span>
        </div>
        
        <div class="column">
            <span>3</span>
        </div>
        
        <div class="column">
            <span>4</span>
        </div>
        
         <div class="column">
            <span>5</span>
        </div>
        
         <div class="column">
            <span>6</span>
        </div>
        
    </div>
    
</div>
