Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web. Bootstrap makes front-end web development faster and easier. It's made for folks of all skill levels, devices of all shapes, and projects of all sizes.
Bootstrap is a front end framework, that is, an interface for the user, unlike the server-side code which resides on the "back end" or server.
