Simple Frontend with Interactive Forms

I’m building a lightweight web interface and want it written in plain HTML5, CSS3, and vanilla JavaScript—no React, Angular, or Vue. The look should stay clean and simple, without elaborate effects or heavy assets.

The heart of the job is a set of interactive forms that validate user input in-browser and give clear, immediate feedback. Smooth field validation, error messages, and a tidy success state are important so the forms feel responsive even though we’re keeping the tech stack minimal.

Deliverables
• Fully coded pages (HTML, CSS, JS) with the interactive forms wired and tested
• Clear comments in the code so I can extend it later
• A short README explaining folder structure and any setup needed to preview locally

Please keep the markup semantic and the CSS well-organized; I value readability over clever hacks. If this sounds straightforward to you, I’m ready to review your approach and timeline.
