• Receive error messages when the form is submitted if:
  • Any input field is empty
  • The card number, expiry date, or CVC fields are in the wrong format
• View the optimal layout depending on their device's screen size
• See hover, active, and focus states for interactive elements on the page

Expected behaviour

• Update the details on the card as the user fills in the fields
• Validate the form fields when the form is submitted
• If there are no errors, display the completed state
• Reset the form when the user clicks "Continue" on the completed state
