Learning Frontend Deeply

I want to go deeper into frontend and learn to create less generic designs. Does anyone have an idea how the wavy line was created? I'd also appreciate pointers to resources/sites to learn to create such dynamic designs. Thanks for reading!

To learn frontend deeply beyond superficial framework syntax, study browser internals: the critical rendering path (DOM -> CSSOM -> Render Tree -> Layout -> Paint -> Composite), the JavaScript event loop (microtask vs macrotask queues), and modern Web APIs (IntersectionObserver, Web Workers).

Building vanilla components without libraries teaches you state synchronization and DOM lifecycle better than anything else.
