Overview

The challenge

Users should be able to:

• View an age in years, months, and days after submitting a valid date through the form
• Receive validation errors if:
  • Any field is empty when the form is submitted
  • The day number is not between 1-31
  • The month number is not between 1-12
  • The year is in the future
  • The date is invalid e.g. 31/04/1991 (there are 30 days in April)
• View the optimal layout for the interface depending on their device's screen size
• See hover and focus states for all interactive elements on the page
• Bonus: See the age numbers animate to their final number when the form is submitted
