How to change styles in CMS moodle?

Question

CMS

Tell me where you can fix the styles, are the images and other parts of the layout related to the theme in MOODLE?
At the moment I found the topic joxi.ru/V2Ve6qVf4EvRmv but physically I can’t figure out where to edit the files.

Answer 1

I must say right away that I didn’t see Moodle in my eyes, but:
1) Look at the elements with the Chrome inspector, see where the files in which they are declared are located
2) Read the documentation https://docs.moodle.org/dev/Creating_a_theme
I doubt that Moodle has some fundamental differences from other php projects
