css3 - 新版支付宝 账单页面滑动时月份栏被下一个月给顶上去是什么效果

Question

上图中，往上滑动时数据加载更多，最先显示当月数据，当加载完当月的，上个月的记录就会上来，且滑动到顶部位置会把当月的给顶上去。
这种效果是如何实现的？能不能给个demo？另问一个，支付宝前端使用了哪种框架？

Answer 1

This client development is mainly based on native, supplemented by web technology. After all, the loading and user experience of web are somewhat different from native.
For an example of this effect on Android, you can check out this open source project https://github.com/emilsjolan...

Answer 2

Are you sure this effect is achieved by the front-end? Android and ios can achieve this effect locally
