What are you most proud of, and what would you do differently next time?

I am able to relearn JavaScript after 7 months of not using it, as well as how to manipulate the style of input element and the error span to produce error messages.

How to align the positions of the input box, submit button and error message and how to use JavaScript to display error message based on input email address.

What specific areas of your project would you like help with?

• A different email verification method, as the current one doesn't check if the address is missing the top-level domain.
