I'm working on a page for a project and I'm using a template that contains CSS and JS files. I wrote the code in Visual Studio Code and it runs fine locally on my computer. I'm using GitHub Pages to share it, but some elements are missing, such as buttons to show/hide the menu, background, and arrows.

This is my repository https://github.com/azu-any/reafo.git

It should look like this: Using VS Code

What is the effect of using GitHub: GitHub Page

Thanks in advance!

PS. I've checked the urls and they are working fine otherwise the other styles won't work.
