The challenge

Users should be able to:

• 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 Screenshot
