For future reference, I would like to make clear that if you use a layout template that matches that of the keyboard you selected, and do not add, delete, or rearrange keys, the legends will appear exactly as they do on kle-render.herokuapp.com, because the exact same code is used to generate them. Please check your layouts before you submit them. Also, it is an unfortunate limitation of the approach I have used that custom CSS styles will likely never be supported, as the parsing is done in python and does not use a browser layout engine
