What is Bootstrap?
Bootstrap is a free and open-source front-end framework used for developing responsive and mobile-first websites and web applications. It includes HTML, CSS, and JavaScript-based design templates for UI components such as buttons, forms, modals, navigation bars, and more.
History of Bootstrap
Bootstrap was developed by Mark Otto and Jacob Thornton at Twitter as an internal tool named “Twitter Blueprint.” It was later released as an open-source project in 2011. Since then, it has grown in popularity and is maintained by the open-source community. The latest version, Bootstrap 5, has dropped dependency on jQuery and supports modern CSS features.
