How does Bootstrap handle flexbox layouts?

Short answer: Bootstrap 5 uses Flexbox by default for its grid system and utilities (.d-flex, .justify-content-*, .align-items-*).

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.
