This page has been cleaned up into a template so you can edit the code to make your own room layout and dress up game.
Right click and inspect to see my code, the javascript is at the bottom of my html file. Read comments for what parts need to be changed.
The overall functionality of this page is that it's broken up into columns that can scroll vertically. You must size your images by screen percentage height (vh) to get things to fit correctly. The dress up functionality only requires that you have all the isolated layers saved at the same size/scale so they fit over each other the way they do in your drawing program.
