为什么git pages呈现的页面不同于本地页面？

我对整个反应性还很陌生，正在接受FCC课程的培训。我的问题来自CSS / SCSS本身。我尝试了普通的CSS和SCSS。我的页面在React中完成。该页面也托管在codepen上。这三个版本都是相同的，分别是codepen，git和local，而CSS之间却有所不同。我以前在这些平台和本地上托管的项目也具有相同的CSS，但它们看起来相同。本地版本和codepen版本之间的区别不是那么大，但是当您下降时，local> codepen> github之间的区别就更加明显了。 GitHub是否忽略/渲染？还是什么，反应不同？这个问题也应适用于Codepen。
