Question

我想使用bootstrap 4 card deck制作响应式fixed width cards。在这里，我发布了下面的代码，但它没有响应原因？

<div class="card-deck">
<div class="card col-lg-2 col-md-3 col-sm-4 col-6" style="max-width: 12rem;">
    <div class="card-body">
        <h4 class="card-title">Title 1</h4>
        <p>Small text here</p>
        <small class="text-muted">3 mins ago</small>
    </div>
</div>
<div class="card col-lg-2 col-md-3 col-sm-4 col-6" style="max-width: 12rem;">
    <div class="card-body">
        <h4 class="card-title">Title 2</h4>
        <p>Small text here</p>
        <small class="text-muted">3 mins ago</small>
    </div>
</div>
<div class="card col-lg-2 col-md-3 col-sm-4 col-6" style="max-width: 12rem;">
    <div class="card-body">
        <h4 class="card-title">Title 3</h4>
        <p>Small text here</p>
        <small class="text-muted">3 mins ago</small>
    </div>
</div>
<div class="card col-lg-2 col-md-3 col-sm-4 col-6" style="max-width: 12rem;">
    <div class="card-body">
        <h4 class="card-title">Title 4</h4>
        <p>Small text here</p>
        <small class="text-muted">3 mins ago</small>
    </div>
</div>

Answer 1

对于带有固定宽度卡的Bootstrap 4卡片组，请执行以下操作：

将每张卡放入一个包含col-auto mb-3类的列（自动宽度列+边距底部为3个单位）。

要将它们居中，请将justify-content-center类添加到该行。

这是一个有效的代码段（点击下面的“运行代码段”并展开到整页）：

Answer 2

在提到的here中，这些布局选项尚未响应。所以我找到了简单的解决方案。将父<div class="card-deck">...</div>更改为<div class="row">...</div>。

感谢您的所有反馈。
