物化卡的高度不相等

Question

我创建了一个Codepen，试图使卡片的高度相等，但是我无法做到。

图片的大小不同，我添加了responsive-img标签。

    <main class="container-fluid">
     <section class="row">
      <div class="col s12 m4 l4">
       <div class="card">
        <div class="card-image">
          <img src="https://unsplash.it/4579/3271?image=1084" class="responsive-img">
          <span class="card-title">Card Title</span>
        </div>
        <div class="card-content">
          <p>I am a very simple card. I am good at containing small bits of information. I am convenient because I require little markup to use effectively.</p>
        </div>
        <div class="card-action">
          <a href="#">This is a link</a>
        </div>
      </div>
    </div>
    <div class="col s12 m4 l4">

Answer 1

默认实现大小

MaterializeCSS为卡提供三种默认大小（小，中和大）。可以按以下方式添加这些内容：（直接从docs的“卡片大小”标题下获取。）

<div class="card small">
    <!-- Card Content -->
</div>

自定义高度

如果所有图像都需要具有相同的高度，并且可以接受固定高度，请将其添加到CSS中：

.card-image{
    height: 400px; /* Your height here */
    overflow: hidden;
}
