Emmanuel Katto : How to Upload My Project to the Internet?

Hi all, I’m Emmanuel Katto, trying to upload my program to my website, but I’m encountering an issue. When I upload the entire project folder, it says the page can’t be found. If I move the resources from the src folder, the page appears, but there’s no functionality—it just displays the HTML and CSS. Can someone help me with a recommendation to ensure everything works as it should when I upload it?

Regards
Emmanuel Katto
