A modern, responsive, and interactive Countdown Timer Application built with HTML, CSS, and JavaScript.
It allows users to create, manage, pause, reset, and delete multiple countdown timers with persistent storage using Local Storage.
Modern Timer is an interactive countdown timer application that allows users to create and manage multiple timers in a clean and responsive interface.
Unlike a basic countdown timer, this project focuses on providing a better user experience through dynamic timer creation, persistent data storage, reusable components, and a modern Glassmorphism-inspired UI.
The application remembers timers using Local Storage, allowing users to continue their sessions even after refreshing the browser.
