Bootstrap

What is it?

Bootstrap was developed at Twitter, and it is something every designer should know.

It lets you build responsive pages quickly and saves a lot of time, because it comes with ready-made templates that help you get the job done fast and efficiently.

It includes a range of tools for building interfaces, which don't necessarily depend on one another.

In the past, the framework had many different tools and libraries, which made it more cumbersome.

Over time, its developers realized they needed to make it easier for users.
