SASS, multiple CSS files when you have many html pages?

I have been trying a lot this morning, and I have this question:

I have many sass files and many html pages. I know how to write the sass on a single css file. But how can I have different css files for every different html page? I don't know if it makes sense to have a huge css file for everything. And I don't know how to split it. These are my scripts, maybe it kinda helps:

So when I compile sass I have main.scss as my input and style.css as my output. Can I have many inputs and many outputs? And if yes, how? You can also send me the documentation if you have a relevant page! Thanks guys.
