css最后一行如何去掉伪类?

Question

一个列表的布局，但最后一个很明显有边框，我不想让他出现。该怎么做呢 ？

.list{
    margin-top: 10px;
    li{
        display: flex;
        justify-content: space-between;
        position: relative;
        padding: 12px 15px;
        background-color: #fff;
        .right{
            font-size: 13px;
            color: #999;
        }
    }
    li:after{
        content: '';
        position: absolute;
        left: 15px;
        right: 0;
        bottom: 0;
        border-bottom: 1px solid #eee;
    }
}

Answer 1

li:last-child:after{
content:'';
border-bottom: 0;
}

Answer 2
