Bootstrap is a popular, open-source HTML, CSS, and JS framework for designing websites and web applications. It's developed at Twitter in 2010 by Mark Otto and Jacob Thornton, and was known as Twitter Blueprint. Bootstrap makes front-end web development faster and easier. It's made for folks of all skill levels, devices of all shapes, and projects of all sizes.

It contains HTML and CSS based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions. Unlike many web frameworks, it concerns itself with front-end development only. Millions of amazing sites across the web are being built with Bootstrap.
