Bootstrap (formerly Twitter Bootstrap) is a free and open-source CSS framework designed for responsive, mobile-first front-end web development. It includes HTML, CSS, and optionally JavaScript-based design templates for common interface components like typography, forms, buttons, and navigation.
Originally developed by Mark Otto and Jacob Thornton at Twitter in 2010, Bootstrap aimed to promote consistency across internal tools. It is an HTML, CSS, and JS library that simplifies the development of informative web pages by providing predefined choices for color, size, font, and layout. Bootstrap also offers a responsive grid system that automatically adjusts web elements based on screen size, and it comes with various pre-styled components and JavaScript plugins for dynamic features.
