【中文标题】您如何在引导程序 4 中正确断点卡片组 [重复]【英文标题】：How do you properly breakpoint a card deck in bootstrap 4 [duplicate] 【发布时间】：2021-06-23 17:00:54 【问题描述】：我见过几个类似的问题，但似乎都没有解决生成的卡片。我的目标是每行有 4 张或更少的卡片，高度/宽度固定。以下是我目前拥有的代码：
<div class="container">
<div class="card-deck">
@foreach (var item in Model)
<div class="card shadow">
<div class="card-title pl-4 pr-4 pt-3">
<h4><a class="stretched-link deco-none font-weight-bold" asp-controller="Home" asp-action="TrainingDetails" asp-route-id="@item.TrainingId">@html.DisplayFor(modelItem => item.Title)</a></h4>
</div>
<div class="card-body overflow pl-4 pr-4 pb-2">
<div class="font-weight-bold text-secondary">
@Convert.ToDateTime(item.DateCreated).ToString("MM/dd/yy")
</div>
@Html.DisplayFor(modelItem => item.Description)
</div>
<div class="card-footer">
<div class="text-center text-muted training-footer">
@Html.DisplayFor(modelItem => item.Topic.Topic)
</div>
</div>
</div>
</div>
</div>
目前它将所有卡片放在一行中，而且每张卡片本身都非常薄。我必须添加什么才能让它分成多行固定大小？ 感谢您的帮助！
【问题讨论】：
【参考方案1】：您可以使用 Bootstrap 的网格系统和 row-cols-1 row-cols-md-2 来定义每个断点处连续有多少张卡片。所有卡片的高度都相同。
