Multi step form using Tailwind CSS and vanilla Javascript

The responsiveness of the form in all steps for different screen sizes. I would make components using tailwind classes for things like buttons, inputs, headings, etc so that it will be cleaner and easier to scale.

The challenge of updating the ui when the plan term is changed. I solved it using objects storing needed data so that I get the data form them and I don't need to do it based on the current state of the text in ui, all I do is to replace it.
