Bootstrap can be useful for the following reasons:
Time savings: Bootstrap features many things that are pre-built, and simply need to be called upon, when writing code. This saves a considerable amount of time, and can greatly reduce the time needed to code a website.
Built with responsive web design in mind: Bootstrap allows web developers to not be concerned about creating things that will scale with the size of their screen, as Bootstrap uses mobile-first, responsive design that allows them to build things that will work on any screen size.
Simplifies design process: Bootstrap comes prebuilt with elements that have good design practices. This can be useful for those whose web design skills are not that great, or for those who view design as a tedious task, as many of Bootstrap classes are aesthetically pleasing and great to look at.
