Bootstrap is a free front-end framework for faster and easier web development. It’s a collection of HTML and CSS-based design templates and JavaScript plugins. Bootstrap provides a set of pre-designed components and layout options, such as buttons, forms, tables, modals, navigation, and more, that can be easily customized and used in web pages.

Bootstrap’s design is based on a responsive grid system, which makes it easy to create mobile-friendly websites. Bootstrap also provides a consistent look and feel across different web browsers, which helps to improve the user experience.

Bootstrap is used by front-end developers to quickly build and customize web applications. It saves time by providing pre-designed components that can be easily modified and integrated into a web page. Bootstrap is also a good choice for developers who are working on a tight deadline, as it allows them to quickly create a functional and aesthetically pleasing website.
