What are keyframes in CSS animations?

Short answer: @keyframes define the steps of an animation over time.

Example code

@keyframes moveBox { 0% { left: 0; } 100% { left: 200px; } } .box { position: relative; animation: moveBox 2s linear infinite; } Follow me on LinkedIn: Key Takeaway: Keyframes control how elements move, rotate, or fade during animation.

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.
