Bootstrap can be quite heavy or lightweight based on how it is used. By default, if you use the complete package you will get tons of features and a bigger code bundle but if you play it smart, you can only include what you need and use, making it super fast and easy to create a website/web app from scratch..

Similarly, do we still need bootstrap? Yes. Once you learn one css framework the skills will easily transfer to others, and Bootstrap is still one of the biggest on the market.

Accordingly, how much time does it take to learn bootstrap?
