我有一台最近制作的老虎机，但我想让它看起来更好一点。https://codesandbox.io/s/slot-machine-xip7x?file=/index.html:0-1480（抱歉，我在将代码复制并粘贴到代码示例中时遇到问题:( 我对此很陌生地点。）这是该代码的结果：https://xip7x.csb.app/每次滚动时，屏幕左侧都会出现一个项目符号点，结果位于中间。当您滚动多次时，新结果只会添加到已有结果中。任何人都可以做到这一点，这样就没有要点，并且每次滚动时它都会替换之前的滚动条并仅显示新的滚动条，因此页面上始终只有一个滚动条。我是编码新手，很想完成这个项目。如果有人能帮助我并解释他们做了什么，我会很高兴。谢谢！
