This project is a fully responsive, front-end authentication system built with HTML, Tailwind CSS, and vanilla JavaScript. It includes essential authentication features such as login, registration, forgot password, and reset password, all styled with a modern UI and smooth animations. The system uses localStorage to simulate user data handling and provides real-time feedback through error and success messages. Designed for educational and demo purposes, it offers a clean code structure and is easy to extend with a real backend for production use. Tailwind CSS is included via CDN, and no external libraries are required beyond that.
