Materialisecss中的卡无法正常工作

Question

我试图用materializecss显示卡片（卡片显示）的内容。参考：http://materializecss.com/cards.html

我创建了三张牌（1行3列）。它在Web视图（pc）中看起来很好。但是在移动视图中，我只需要以小尺寸显示它以使其适合精确的视口。但是，我不想在移动视图中将这些卡显示在多行中。我尝试过这个。但是，徒劳无功。不知道我做错了什么？

此外，当我单击卡中的选项图标时，我看不到内容。

这是当前的结果：

我的代码：

 <div class="parallax-container" id="abc" style="height:auto">
        <div class="section">
            <div class="container">

Answer 1

您已经定义了s12，这意味着一行中的一张卡，即一张卡需要一个完整的宽度。使它成为s4然后将在一行中有3张卡而不是多行，然后使用媒体查询为小屏幕制作样式。您可以查看更新的code here

对于媒体查询：reference

Answer 2

使用jQuery 3和Materialize 0.100.2在干净的codepen中无法重现此行为。
