Unless you want to try to get some of those “web3” (really just mostly brute-forcing hashes for income) bounties on replit, it’s not even worth trying to.
Both CSS and Javascript animations are a quagmire, so it’s better to use an IDE like Rive.app ; GlowScript.org ; or even Adobe Animate. Even the expired “Flash mx 2004” offers smoother development experience than CSS/JS animations.
Also, learn C programming to code in CGo, making your GoLang programs (incl. gRPC API calls) much faster, with C libraries.
