How to access main.css file?

Hiya, I’m quite new to so bear with me.
When I go appearance → editor I can find a bunch of .php files as well as one style.css file at the very bottom which contains no actual code and is a bit of a disclaimer.

where exactly do I find these files?

Detailed help would be much appreciated, thanks.

Hello @samsaga1307,

The default style.css is just importing the other main files.

In order to access the main.css file, you need to access the FTP server where your WordPress installation can be found and there you can navigate to wp-content > themes > illdy > layout > css > main.css

Let me know if you got this alright.
