Hello! We don't offer that type of course specifically, sorry, although we may have some beginner courses that'd help
You may be able to get started with a couple of our courses here that use SVG, our Adventures in Web Animations course and our You, Me & SVG course. They don't cover 3d animation, though, and although I don't think SVG is used for really intensive 3d animations, I think it can be, at least in part.
There may be other ways to do online, website-based 3d animation, though, so I'd also do a bit more research, and you can use the above as starting points for that research too!
