I built SpartanOS, a WebOS-style webpage with multiple draggable windows that can be opened and moved around the screen like a lightweight desktop environment. The main challenge was getting smooth window dragging working properly while managing layering so windows don’t overlap incorrectly or break when multiple are open. I’m proud that I was able to turn it into a functional multi-window system that feels like a real interface rather than just separate UI elements, and I also added features beyond the guide like improved window behavior and interaction handling. You can test it directly in the browser with no password by opening multiple windows, dragging them around, and interacting with them to see how the system handles layering and movement.
