How can I make my site in git-pages recognize the files that are inside the css, img and js folders?

Well, I'm trying to upload a site to git-pages, but I can not get it to recognize my .css, .js, .png, and .jpg files that are in the css, js, and img folders, and this does that the pages stay in pure html.

I have tried to leave the files right in the branch and only change the path in href, and this worked, but it would not be ideal for me.

Sitelink: link As you can see, no image has been uploaded and the home page is only formatted because I've moved the .css file.
