How to Share My Project on the Internet?

Hi there, I’m having trouble uploading my project to my website. When I upload the complete project folder, it shows an error saying the page can’t be found. However, when I move resources out of the src folder, I can see the page, but there’s no functionality—it only loads the HTML and CSS. I’d appreciate any recommendations on how to make my program work properly once uploaded.

Regards
