§ Design

  • don’t prompt before interaction or during critical tasks

    • prompt after user has completed a significant action

    • do not interrupt your users

  • don’t impede transitions or access to content

    • user’s task is to read the content, don’t get in the way

  • don’t assume a modal overlay will deliver the message

    • People are used to close popups immediately without even reading the text. If you have something important to say, use other methods to show it. (e.g., non-intrusive overlays at bottom or side of the page)
