实现思路:
1.给需要添加边框的元素进行定位
2.通过给定位的元素添加伪元素::after ::before
3.通过改变伪元素的top,left,right,bottom值来实现边框
只保留下边框,只需将top,left,right都设置为0
.box::before, .box::after { transform: all .3s; position: absolute; content: ""
; top: 0; right: 0; bottom: -2px; left: 0; background: linear-gradient(45deg,
rgba(247, 7, 7, 0.8),rgb(231, 216, 4),rgb(0, 255, 0)); z-index:-1; box-sizing:
border-box; }
