Learning and bundling with webpack

Hello good afternoon, is there someone who knows about webpack? The question is that I have finished my random quote machine and once I compile it it works correctly on the localhost. I have uploaded it to my github and I wanted to put it in netlify and the case esq everything works except the css, I can not see any style and I can not understand what is happening since I am still something new. Thank you very much for your time and attention.

How are you including your css?

Css styles are good, you can try it forcing from the github and launching a yarn start see how the styles work, pass the tests and if you change the call time to the app and put it slower gives you bad response

I thought this was a pretty good series on webpack
