Bootstrap

Bootstrap

• Bootstrap is a free and open source front end development framework for the creation of websites and web apps.

•  The Bootstrap framework is built on HTML, CSS, and JavaScript (JS) to facilitate the development of responsive, mobile-first sites and apps.

• Responsive design makes it possible for a web page or app to detect the visitor’s screen size and orientation

•  automatically adapt the display accordingly; the mobile first approach assumes that smartphones, tablets and task-specific mobile apps are employees' primary tools for getting work done and addresses the requirements of those technologies in design.

• Bootstrap includes user interface components, layouts and JS tools along with the framework for implementation. 

• The software is available recompiled or as source code.

• Mark Otto and Jacob Thornton developed Bootstrap at Twitter as a means of improving the consistency of tools used on the site and reducing maintenance.

•  The software was formerly known as Twitter Blueprint and is sometimes referred to as Twitter Bootstrap.

• In computers, the word bootstrap means to boot: to load a program into a computer using a much smaller initial program to load in the desired program (which is usually an operating system).
