What I learned

With this project I learned a little bit more of absolute positioning, in order to position the card images and filling the card data with the form inputs.

Continued development

I'm planning to continue with trying other JavaScript frameworks like astro or svelte and working with public APIs.

Useful resources

• Hide arrow number - Little information for hiding numeric inputs steppers.

• Check if variable is a number in Javascript - This is an amazing article which helped me determined that the card number is effectively a number (not strings or other data types)
