How do I turn my offline collecting game into an online multiplayer game?

Question

Well I have a site I coded ( https://lifewitgray.github.io/Cubey/ ) and I wanted to turn it into an online multiplayer game with trading, jackpots, and live chat (Please use website linked above to understand what I mean). How would I approach this? I have very little knowledge of coding and this site as it is now took me almost 4 months. I think it would be cool to expand it, so if anyone could help that would be amazing!

Learn three whales of web development(actually nowadays they are just basics =), but still):
Html
CSS
JS
JavaScript with some handy libraries can do the job you want to perform.
