PROJECT CHECKPOINT

Turn css and responsive design into evidence

Turn the profile into a responsive landing page with reusable design tokens.

  • Write acceptance criteria for cascade layers before implementation.
  • Keep the change small enough that a reviewer can connect it to the intended behavior.
  • Use the most direct check available for specificity and save the result.
  • Record one decision you would keep and one you would revisit after feedback.
