如何在引导程序 4 中包装（浮动）卡片答案

【问题标题】：How to wrap (float) cards in bootstrap 4如何在引导程序 4 中包装（浮动）卡片
【发布时间】：2022-01-22 06:19:26
【问题描述】：

我正在使用 bootstrap 4 beta。

我有一张卡片清单。我希望它们具有固定宽度，但高度会根据内容而变化。

卡片的数量可以从1到n。

我想要的效果是卡片从左到右排列，直到屏幕空间用完，然后换行到下一行。

我已经尝试了 bootstrap 4 示例页面上列出的所有不同的卡片选项，但它们似乎没有换行。

我怎样才能做到这一点？

下面的例子显示了它们 3 对面，它们之间有很多空间。

 <div class="card-columns">

        <div class="card" style="width: 18rem;">
            <img class="card-img-top" data-src="..." alt="Card image cap">

                <h4 class="card-title">Card title</h4>
                <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>

请分享您的代码？

【解决方案1】：

在使用了一段时间后，我想出的浮动解决方案并不令人满意，因为在某些情况下，某些卡片下方有大量空间。在查看 bootstrap 4 卡片后，我发现了一个完全可以做到的功能我想要它：“卡片列”

它将您的卡片排列成三列，并在屏幕尺寸较小时重新排列成一列。

【讨论】：

谢谢伙计。你在那里为我节省了大量时间。
我发现卡片列的唯一问题是顺序。如果您在 3 列中有 15 张卡片，则页面顶部的卡片将类似于卡片 1、卡片 6 和卡片 11。不太好！
Bootstrap 4.1 链接：getbootstrap.com/docs/4.1/components/card/#card-columns
感谢分享格雷格！我要头疼了
这在 Bootstrap 5 中不起作用是吗？

【解决方案2】：

我想出了一个有效的浮动卡片类：

<style>
    .floating-card {
        float: left;
        margin: 5px;
        max-width: 300px;

    }
</style>

示例用法：

    <div class="floating-card sortable">
    <section class="box-typical task-card task">
        <div class="task-card-photo">
            <img src="img/img-task.jpg" alt="">
        </div>
        <div class="task-card-in">
            <div class="btn-group task-card-menu">
                <button type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    <i class="font-icon-dots-vert-square"></i>
                </button>
                <div class="dropdown-menu dropdown-menu-right">
                    <a class="dropdown-item" href="#"><i class="font-icon font-icon-pencil"></i>Edit</a>
                    <a class="dropdown-item" href="#"><i class="font-icon font-icon-archive"></i>Archive</a>
                    <a class="dropdown-item" href="#"><i class="font-icon font-icon-trash"></i>Delete</a>

            <div class="task-card-title">

                <span class="task-card-title-label">(BIG)</span>
            </div>
            <div class="progress-compact-style">
                <progress class="progress" value="25" max="100">
                    <div class="progress">

                    </div>

        </div>
    </section><!--.task-card-->
</div>

【解决方案3】：

这里的解决方案... 使用引导行和列来实现这一点，请按照下面的代码。

<div class="row">
 <div class="col-lg-4 col-md-3 col-sm-6">
   <div class="card">
      <img class="card-img-top" data-src="..." alt="Card image cap">
      <div class="card-block">
         <h4 class="card-title">Card title</h4>
         <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
          <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
      </div>
    </div>
 </div>
</div>

【讨论】：

我试过了，它把它们放在一个水平列中。
从'card' div和行和col的标记中删除宽度

【解决方案4】：

根据 Srikanth 的建议，您可以使用以下代码。您可以调整class="col-lg-3 col-md-4 col-sm-6 以根据浏览器的宽度显示更多或更少的卡片。我还包括一个宽度显示来显示像素宽度。

当然要调整php循环数量来测试卡的数量或多或少。

<body>        
    <center>Width: <span id="width"></span></center>
    <br>
    <div class="container">            
        <div class="row">
<?php    
    for ($x = 0; $x <= 10; $x++) {
        $card = <<<EOF
            <div class="col-lg-3 col-md-4 col-sm-6" style="margin-bottom:10px;">
                <div class="card">
                     <img class="card-img-top" src="your_image.jpg" alt="Card image cap">
                     <div class="card-block" style="margin:5px;">
                         <h4 class="card-title">Card title {$x}</h4>
                         <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
                         <center class="link">Join</center>
                     </div>      
                 </div>
            </div>
EOF;
      echo $card;
    }    
?>     
        </div>   
    </div>
<script>
$(window).resize(function() {
    var viewportWidth = $(window).width();
    $('#width').html(viewportWidth);    
});
</script>
</body>

在 5.1 版中，Bootstrap 已经远离了在 4 版中使用的 CSS 技术。Here 他们提供了一个如何使用 Masonry 插件的示例，请参阅这个 sn-p：

有趣。这是我第一次听说 Masonry，但就像你说的，Bootstrap 文档显示它与 Bootstrap 一起使用。
