Frameworks like this and other similar non-standard approaches like Elixir Phoenix and LiveView are awesome, however, I'm still lost as to how one should go about styling and / or dynamically structuring styling?

Does anyone have recommendations for guides or simple approaches that only focus on the pure UI side of the problem. I've never really "had" to learn JS and honestly every time I have to dip my toes in it leaves a very bad taste in my mouth.
