Newsletter singup form with success message

Hello, another challenge I completed in mobile first approach.

I don't know what are needed breakpoints for responsive view but on this challenge I have breakpoint for 760px, because it looked bad with desktop design between 480px and 760px.

In this challenge I focused on managing form inputs in good way.

I used aria-describedBy attributes to manage input errors.

I would be very gratefull for feedback and tips, especially in javascript that I refactored with a little of chatGPT help :)
