Welcome! I hope that you are enjoying HTML and CSS! (I know that I do). If you haven't come across it yet in your resource hunting, check out Codepen. That will give you a whole bunch of stuff that you will want to learn! There are other sites as well, but this rabbit hole only gets deeper.
You have been warned lol
(This coming from someone that is trying to figure out where to start learning JS lol)
Good luck in your journey!:)
