Css Flexbox, Module Css

What specific areas of your project would you like help with?

"I had problems when deploying the project because the index.module.css was not detected globally, and I had to repeat the variables in each of the existing CSS files in the project. I don't know why this happens. I've been using TypeScript for a short time, and I would like to know if there is a specific way for the index.module.css to be detected globally in the other CSS files when deploying the project on GitHub Pages or Netlify."
