使用element的提示框并修改css

 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;
}
