About
Bootstrap is an open-source framework for building responsive, mobile-first websites and web applications with 
HTML, 
CSS, and 
JavaScript, originally developed at Twitter.
It provides a responsive grid system, prebuilt components, extensive 
Sass variables and mixins, official icon library, and built-in form validation.
The GOV.UK Design System is an open-source design system that provides styles, components, and patterns to help UK government teams build consistent, user-centered digital services.
It includes reusable and accessible UI components for forms, navigation, and content, documented patterns for common user tasks, and design guidance for layout, typography, and color, with code examples released under an 
MIT license and regularly tested to meet 
WCAG 2.2 AA accessibility standards.
