What are vendor prefixes?

Short answer: Prefixes ensure CSS works across browsers before full support.

Example code

Follow me on LinkedIn: .box { webkit-border-radius: 10px; /* Chrome, Safari */ moz-border-radius: 10px; /* Firefox */ border-radius: 10px; /* Standard */ } Key Takeaway: Vendor prefixes provide cross-browser compatibility for experimental features. Intermediate

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.
