Contribute to make KA Lite accessible to all

Why

Because inclusive design benefits all users!

  • Ensuring that KA Lite is easily navigable with the keyboard will help blind users AND those who cannot use the mouse (or just prefer using the keyboard most of the time).
  • Using the appropriate color contrast or making available a high contrast version of KA Lite content will benefit the users with low vision AND all those who need to use it in highly illuminated settings.
  • Offering captions and transcripts for KA Lite video content will benefit auditory challenged audience AND improve its comprehension for everybody.
  • Maintaining consistent structure, navigation and language will reduce cognitive load for all the audiences AND make it easier for KA Lite content to be localized.

tota11y presents as a small button in the bottom left corner of the document you are viewing.
