Bootstrap is a popular open-source front-end framework used for building responsive and mobile-first web applications and websites. It was originally developed by Twitter, and it's now maintained by a community of developers. Bootstrap provides a collection of pre-designed HTML, CSS, and JavaScript components and tools that simplify web development and help create modern, visually appealing, and consistent user interfaces.
Responsive Design: Bootstrap is designed with responsive web design in mind. It uses a mobile-first approach, meaning that web pages are first designed for mobile devices and then progressively enhanced for larger screens. This ensures that your website looks good and functions well on various devices and screen sizes.
