How to change the website background in leopard?

I used leopard to convert my scratch game and got rid of the borders which works fine, still you can see separation. I've tried overwriting it with css, didn't work.

I'm not sure this actually has to do with Leopard, a code comment in the file you linked said it was generated with Turbowarp? That's another project by a whole different team of folk. I'm late to this issue anyway, but you'd have to check in with the developers there to get the best support relevant to your project.
