Bootstrap v4.5使卡片大小相同[重复]

Question

首先，如果某个地方已经有这个问题的答案，我很抱歉。如果是这样，请向我指出那个方向。我一直在寻找一段时间，但似乎无法找到符合我需要的答案。

我正在尝试使我的heroku page 上的所有引导卡都具有相同的大小。我将它与围绕响应式 div 的容器一起设置为 display flex 和 justify-content-center 和 align-items-center。我也尝试过 align-items-stretch ，但它仍然不会导致卡片的高度相同。我还尝试在行内的响应式 div 上使用引导高度实用程序 (h-100)。也使用了 css min-height 但遇到了问题，因为在调整窗口大小时内容会溢出 div。

这是我目前所拥有的，最终会根据内容使用不同大小的卡片：

<div class='home-container m-5'>
    <div class="row d-flex mb-5 justify-content-center align-items-center">
        <div class="col-sm-6 col-lg-4">
            <a href='./Multi-welders'>
                <div class='card m-3 bg-light'>
                    <img src="./images/Home/Multi_Welder2.png" alt="ESAB Rebel EMP215IC welder" class="card-img-top pl-md-2 pt-2 pr-md-2 mx-auto">

Answer 1

您可以添加以下css类：

.card {
  height: 200px
}

这将使您的所有卡片具有相同的高度。你可以随意改变高度。
