效果如图所示：

思路：

使用元素覆盖的方式实现视觉上虚线的效果

实现代码：

html布局

html 复制代码

<ul class="details-cont">
    <li class="details-li" v-for="item in 3" :key="item">
        <div class="li-status">{{ item }}</div>
        <div class="li-flow-box">
            <div class="flow-circle"></div>
            <div class="flow-line"></div>
            <div class="flow-line-other"></div>
        </div>
        <div class="li-details">
            <div class="details-top">文字</div>
            <div class="details-channel">文字文字文字</div>
            <div class="details-stream">文字文字文字文字</div>
        </div>
    </li>
</ul>

                height: rem(8);
                border-radius: 50%;

                top: rem(13);
                bottom: rem(-23);
                width: 1px;
                border-left: 1px dashed #D7D7D7;
            }
        }
        .li-details{
            flex: 1;
            font-size: rem(12);
            color: #999999;
            line-height: 18px;
            .details-channel,.details-stream{
                padding: rem(6) 0 0;
            }
        }
    }
    .details-li:last-child{
        .li-flow-box{
            .flow-line-other{
                position: absolute;
                left: rem(9);
                top: rem(13);
                bottom: rem(-23);
                width: 1px;
                border-left: 1px dashed #fff;
            }
            .flow-line{
                border-image: linear-gradient(180deg, rgba(215, 215, 215, 1), rgba(237, 237, 237, 0.49), rgba(215, 215, 215, 0)) 1 1
                
            }
        }
    }
}

PS：因为在移动端使用，单位代码使用统一的方法对rem进行了处理，此处rem(1)，就相当于1px，
