Incorrect CSS when React App is deployed with GitHub Pages

The Login page of my application looks like this while on local host. But when I deployed my application with GitHub Pages, it looked like this.

Link of the Application:
Link to my repo:

I am not familiarized with deploying applications so I am writing this question in hope that this problem has occurred to more people, and that someone could point me to what should I have a look at in my application.

In a similar question, someone pointed the solution to a specific configuration in the package.json file. Couldn’t find anything but am putting it below if it could help anyone.

  1. I am using the same browser when developing as when testing the deployed page.
  2. I don’t have any styling-related extensions on my browser.
  3. I am using pure CSS.

Thanks in advance.
