Device Detector Tool Using HTML, CSS and JavaScript with Source Code


Welcome to the Device Detector Tool, a web-based application designed to identify and display the user's operating system and browser. This tool leverages modern web technologies, including HTML, CSS, and JavaScript, to provide an intuitive and interactive experience. With its sleek design and engaging loader animation, the Device Detector Tool offers users a seamless way to gain insights into their device's specifications.

The project highlights the practical application of client-side detection, showcasing the power of JavaScript in dynamically identifying and displaying device information. HTML structures the content, CSS enhances the visual appeal with a gradient background and smooth animations, and JavaScript handles the core detection functionality. This combination of technologies results in a responsive and user-friendly interface, making the Device Detector Tool both educational and functional.
