使用el-tooltip来做提示框：

<el-tooltip popper-class="popper" content="敬请期待" placement="right"><div><i class="iconfont icon-lianjie-01"></i><span>输入链接</span></div>
</el-tooltip>

去掉默认小三角和背景样式：

.popper {width: 268.5px !important;background: #F0F0F0 !important;font-weight: 400 !important;font-size: 12px !important;color: #333333 !important;padding: 14px 22px !important;border: 1px solid #E8E8E8 !important;
}.popper .popper__arrow::after, 
.popper .popper__arrow {border-right-color: #F0F0F0 !important;
}
