My process

Built with

• Javascript
• CSS
• Mobile-first workflow
• React - JS library
• React Hook Form - React hook to handle and validate form data

What I learned

• I learn how to mask text data to show only what you need. For example in the credit card number the space every four numbers its only visual.
• I learn to validate inputs and render error messages to wrong format inputs using react hook form.
• It was painfull to get back with only css to style this project, i started naming all the clases without BEM rules and very quickly turn into a lot of classes that makes the responsive part more dificult, this was a very good learning of what no do ever again. Next project i will use SASS for the styling.
