None of the boxes is moving around.

You have created five JS files that are not useful at all. It's not doing anything in the index.html file. Please remove all unnecessary code which not useful at all @BWbwchen

Start by inspecting index.html and the repository's five JavaScript files, then check which files and code are actually referenced. Done means removing code that is demonstrably unused without removing anything required by index.html; the issue does not identify the files or a more specific expected result.
