“Begginer here”

I create multiple pages (HTML elements) in 1 project folder with 4 menu navigations.

• index
• aboutme
• portfolio
• contactme

The 3 pages where inside a separate folder for organization purposes.
root (index)
folder (3 pages)
folder (images)

When uploaded in github, on the public page, only the homepage(index) were functional or displayed. When clicked to the other page link in the in nav menu, it returns 404 pages.

1st try:
I moved the 3 HTML files outside the folder. (Failed)

2nd (thought process)
I would create a separate repository for each html pages? I don’t think if it is the right way since I want the 4 pages interact as 1 website function or in 1 repository.
