HMRC is retiring Assets Frontend following the launch of HMRC Design Patterns. Assets Frontend is still available for services that use it but it will not be developed further. HMRC will maintain it and roll out major bug fixes and security patches.
For new projects that use the latest GOV.UK Prototype Kit, use HMRC Design Patterns to get patterns and code designed specifically for HMRC and for patterns not yet in the GOV.UK Design System.
Only use these components and patterns for HMRC services built with Assets Frontend versions 3 and 4.
If you are maintaining a service that still uses an earlier version of Assets Frontend, use the Component Library.
The core styles that will make your service look and feel like GOV.UK. This includes Colour, Typography and Layout.
Best practice design solutions for specific user-focused tasks and scenarios.
