How do you implement animations in CSS?

Short answer: Use @keyframes and the animation property.

Example code

@keyframes fadeIn { from { opacity: 0; } to { opacity: 1; } } .box { animation: fadeIn 2s ease-in-out; } Follow me on LinkedIn: Key Takeaway: @keyframes define the animation steps; animation applies them.

Real-world example (ShopNest)

ShopNest’s browser cart uses modern JavaScript: fetch APIs with async/await, modules, and clear error handling.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
