git – Problema ao postar projeto no GitHub

Estou tentando publicar um novo projeto no GitHub.

Porém, quando faço o download do projeto e abro o index.html, aparece apenas o HTML puro
sem o CSS e JS.

Mas, as pastas CSS e JS aparecem dentro do projeto.

Link do meu projeto: https://github.com/KellymaryAraujo/interactiveLoginScreen

Publiquei ele assim no terminal bash do VS Code:

Kelly@DESKTOP-EVPORTF MINGW64 ~/Desktop/loginscreen
$ git init
Initialized empty Git repository in C:/Users/Kelly/Desktop/loginscreen/.git/

Kelly@DESKTOP-EVPORTF MINGW64 ~/Desktop/loginscreen (master)
$ git status
On branch master

No commits yet  

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        css/
        index.html
        js/

nothing added to commit but untracked files present (use "git add" to track)

Kelly@DESKTOP-EVPORTF MINGW64 ~/Desktop/loginscreen (master)
$ git add .

Kelly@DESKTOP-EVPORTF MINGW64 ~/Desktop/loginscreen (master)
$ git commit -m "First Commit"
