apparently you can check where the browser window is relative to the screen that it's on, so I had this very cursed idea and that is to make a webpage that has a fixed position on your screen (rather than in the browser window) and the browser window is like a magnifying glass that you have to decrease the size of to bring the page in focus, and then you have to move the window around to find the different sections of the page like a point and click adventure.
lmao this is the worst idea ever @lina
