Bootstrap is a comprehensive front-end toolkit for building responsive and mobile-first web projects. It provides a robust grid system, extensive pre-built UI components, and a powerful utility API for rapid styling. Built with Sass, it allows for deep customization through variables and mixins. The framework includes a suite of JavaScript plugins that function without jQuery, utilizing data attributes for easy integration. It is highly modular, allowing developers to import only necessary parts.
