How to connect css to html page on your Http Server?

Question

Web servers

I am writing my own http server. I wrote my own get method, but I still don’t understand how to pass css to the html page?
Do I need to send two responses? One with html and one with css? Or somehow differently? If there are two answers, then what should the http-header look like?

Answer 1

If the styles are not built directly into the html file, then css is just a resource on the server, like an html page, like pictures or js scripts. The browser itself makes a request to the address specified in the Html tag on the page. The server should only return the correct mime type for the file.
