Newsletter Form with TailwindCSS and JS Live Validation

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

I’m most proud of successfully implementing form validation with live feedback and a success page redirect. I also paid attention to accessibility by using proper labels, error messages, and ARIA attributes. Seeing everything come together with Tailwind for styling made me feel like I’m getting better at writing clean and structured code.

What challenges did you encounter, and how did you overcome them?

One big challenge was getting the form validation right—especially checking for empty values, validating emails, and showing/removing error styles dynamically. I solved this by breaking the logic into smaller functions and testing step by step.

Another challenge was hiding the email in the URL after redirecting to the success page. I overcame this by learning about the history.replaceState method, which let me display the email but clean up the URL for better security and user experience.

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

I’d like help with:

Writing shorter, cleaner validation code (maybe with regex or built-in validation features).

Best practices for accessibility when handling error messages and success states.

Suggestions on how to make my code more reusable and scalable for bigger projects.
