如何改变背景时，我悬停卡？

Question

当我在卡片上盘旋时，我想改变背景。我曾试图添加悬浮类，但它不起作用，所以我现在在这里创建这个社区。

我想在背景中添加任何颜色。很抱歉，我发布这个问题的方式给我带来不便。这是我的第一个问题。提前谢谢。

Answer 1

如果您希望在悬停时更改卡的背景，可以将其添加到css中：

.card-container:hover {
    background: cadetblue;
  }

Answer 2

使用这个

.showcase .card-1:hover{
background-color:green;
}

Answer 3

您可以使用:hover状态在卡上添加悬停效果。

.card-container:hover {
    background: green;
}
