3d名片悬浮css

效果演示

在这里插入图片描述

实现原理

给卡片添加 css3 新的过度属性（transition），鼠标移入和移出时都会触发这个过度属性，使卡片向上偏移一段距离，同时扩大卡片的背景阴影，从而实现卡片的浮动效果。

关键代码

.card-box .card {
    transition: transform .2s, box-shadow .2s;
    /* 省略部分代码 */
}
.card-box .card:hover {
    transition: transform .2s, box-shadow .2s;
    transform: translateY(-4px);
    box-shadow: 4px 4px 8px rgba(0, 0, 0, .1), -4px -4px 8px rgba(0, 0, 0, .1);
}
