Interactive form for registering credit card details - On input, data are shown on a card visualisation next to the form. Responsive design for mobile and PC view.

Two-sided design. Floating cards' visualisation was a bit demanding, especially with the responsive design.

Testing both FlexBox and Grid - I'm comfortable with flexbox and I wanted to practice other displays. Styling for form errors and controlling succesful form submission.

A script for controlling form actions (error/success) and displaying success page (hiding the form class and showing the success one).
