GoopOS

I made goopOS, a browser-based mock operating system built with HTML, CSS, and JavaScript that includes draggable windows, a taskbar, and simple apps like a notepad and embedded Google browser. The main challenge was building a stable window system with proper dragging, layering, and open/close behavior without bugs or animation issues, as it took me quite a long time to figure out pseudoclasses. I’m proud of how it now feels like a real desktop environment with smooth interactions and working taskbar controls. To test it, open the site and use the top bar icons to launch apps, drag windows around, and close or reopen them from the taskbar.
