How do you use Bootstrap utilities for spacing and alignment?

Short answer: Use margin (m-*) and padding (p-*) utilities: <div class="p-3 m-2 text-center"></div>

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.
