It's all open source and in the public domain: https://github.com/18F/web-design-standards https://github.com/18F/web-design-standards They're also pretty active with the pull request system: https://github.com/18F/web-design-standards/pulls https://github.com/18F/web-design-standards/pulls and have a CONTRIBUTING guide: https://github.com/18F/web-design-standards/blob/18f-pages-staging/CONTRIBUTING.md https://github.com/18F/web-design-standards/blob/18f-pages-s...
