How do some sites (like GitHub) include *.scss files directly?

Question

css

Hello!
I noticed that some sites connect *.scss files directly to the site:

How do they do it?

Answer 1

To facilitate debugging and troubleshooting, browsers support "maps" that allow you to get the line number in the source file from the line in the compiled / minified file.
You can read about it, for example, here: blog.teamtreehouse.com/introduction-source-maps

Answer 2

This is just a .css map, no one directly connects .scss, you can open the source code of the same github, from the styles there are only 2 .css files, at the end of which you can find a link to the maps themselves prntscr.com/jng5n3

Answer 3

This is either assembled on their host, or this is a map of the source file
