How does the grid system work in Bootstrap?

Short answer: Bootstrap uses a 12-column grid based on flexbox. You divide your layout using .row and .col-* classes. Follow me on LinkedIn: <div class="row"> <div class="col-6">Half</div> <div class="col-6">Half</div> </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.
