react 使用react-seamless-scroll实现无缝滚动

1. 实现无缝滚动效果

1. 实现单步向下滚动
2. 点击更多展开，收起，调整 scroll 高度

2. react-seamless-scroll 无缝滚动案例介绍

1. 项目地址 react-seamless-scroll
2. 拉下来跑起来效果（gif录屏有点卡，实际很丝滑）
   
3. 可以支持多种无缝滚动方案，如 向下滚动，向左滚动，滚动速度，鼠标悬停，单布停顿，单行停顿时间，数组属性更新，数组添加数据，图表滚动 等
4. react-seamless-scroll 无缝滚动有两种实现方式，一种是 cssSeamlessScroll，另外一种是 jsSeamlessScroll

3. react 项目集成

3.1 项目引入 cssSeamlessScroll 滚动组件

1.这里我使用的 cssSeamlessScroll 的。
2. 将 cssSeamlessScroll 组件 的代码复制到项目中
