Why high-frame-rate interactions and buttery transitions are more than just eye candy.
Beyond Aesthetics
When we talk about "smoothness" in UI design, it's easy to dismiss it as mere decoration. However, biological research suggests that our brains process smooth, 60fps+ animations as "natural" and "safe," while jittery or lagging UI triggers subtle stress responses.
The Mechanics of Feel
Achieving true smoothness requires a deep understanding of browser rendering constraints, CSS transforms vs. layout recalculations, and advanced physics engines like Framer Motion to create spring animations that feel physically grounded.
