## What it is
GOV.UK Frontend is a design system framework providing CSS, JavaScript, Nunjucks macros, and assets for building consistent, accessible UK government digital services. It is maintained by the Government Digital Service and helps services meet WCAG 2.2 level AA.

## Use cases
- build a user interface for a UK government service
- make my service meet WCAG 2.2 AA accessibility
- get GOV.UK styled components like buttons and accordions
- create a consistent design system for public sector websites
- replace the old GOV.UK Template or GOV.UK Elements
- use Nunjucks macros to render government form components

## When to choose
- building a service on the GOV.UK platform or a UK public sector service
- you need accessible, tested UI components with broad browser and assistive technology support
- you want to comply with the GOV.UK Design System and Service Manual

## When to avoid
- building a non-government product with its own brand identity
- you need a full JavaScript application framework rather than CSS/HTML components
- your project relies on LibSass or Ruby Sass with version 6+

- artifact type: framework
- maturity: stable
- function: ui-components, css-framework, frontend-framework, templating, accessibility
- domain: web-development, frontend, web-design, e-government, accessibility
