Bootstrap
Bootstrap was originally developed by Twitter and is now one of the most popular tools for modern web design and development. It features a responsive 12-column grid system, utility classes, UI components like buttons and modals, and JavaScript plugins. With Bootstrap, developers can rapidly build consistent and mobile-friendly websites without writing custom CSS from scratch. Its open-source nature and strong community support make it easy to customize and extend.
Bootstrap includes templates and themes that help reduce development time while maintaining design consistency across browsers and devices. The framework is widely used in both personal projects and enterprise-grade applications.
It’s compatible with all major browsers and supports accessibility standards. As of version 5, Bootstrap no longer depends on jQuery and introduces improved support for CSS variables and custom components.
