UK Government Design System

Mikes Notes

The UK Government has created a design system for building accessible websites. There is a wealth of templates, components, tools, code and guidance on how to do this.










I am using this design system as a starting point for making the Pipi User Interface (UI) fully accessible.

Please note: This blog is for a technical audience and is to help Mike (me), who has synesthesia (that's why everything is colour-coded), keep notes and share them with collaborators. This blog is not intended to be accessible.

User Testing

Assume every person is unique and allow for personalisation. W3C WCAG 2.1 is the standard to aim for. Accessibility testing is underway in English for,

The current testing process steps are,

  1. Speak to groups of people and their organisations with everyday accessibility needs. Ask for volunteers.
  2. Watch and learn from people who volunteer with accessible needs. How do they find using a computer to visit and use a website? What are the problems? What works?
  3. Use personalised handmade web pages for volunteers to test.
  4. Configure the Content Management System (CMS) to generate the web UI automatically to meet the individual accessibility needs of logged-in users.

UK Gov Design System

The UK government's design principles and examples of their use.

  1. Start with user needs
  2. Do less
  3. Design with data
  4. Do the hard work to make it simple
  5. Iterate. Then iterate again
  6. This is for everyone
  7. Understand context
  8. Build digital services, not websites
  9. Be consistent, not uniform
  10. Make things open: it makes things better
The Design System components are reusable parts of the user interface that have been made to support various applications.
