Hack Day for MDN Web Docs

taught by: MDN Web Docs Team


Come help improve accessibility on MDN Web Docs! You can contribute to content about accessibility, and/or the accessibility of the site itself. This all-day session will be a mini version of the Hack on MDN for Accessibility, held last September in London.

MDN Web Docs ( is a source of references, guides, and tutorials on standards-based web technologies, much loved by web developers. It was chosen as #1 for Documentation in the Developer’s Choice Awards for 2018, conducted by SlashData.

Yet, MDN Web Docs needs help from accessibility experts and enthusiasts—whether you are a programmer, designer, or someone else who cares about accessibility. Significant chunks of the accessibility docs on MDN need creating, updating, improving, and translating. The accessibility of the site itself also has some issues. MDN is a wiki, so anyone can contribute to content.

During this full-day hackathon, you will become familiar with how to contribute to MDN, and have fun collaborating with other participants.


For this full-day session, we are looking for help from participants with any of the skills listed below. Note that you need not be an expert to contribute.

  • Knowledge of accessibility standards and practices
  • Accessibility testing
  • Front-end web development
  • Editing
  • Native fluency in a language other than English


  • A laptop for you to work on
  • A GitHub account, as this is used for authentication to MDN
