Does anyone know how to make an image fit to the size of the background of the palette? If that makes sense?

i dont think there is a direct way for the image to perfectly fi the background of this game

I don't check this often, sorry about that.

What's the code for fitting an image to a palette so it doesn't get blurry? Also, how do you keep the header from scrolling down the image when you scroll?

for the first question, try the following. The | just separates the different options you can use:

background-size: cover | x% | # px

How do I get rid of this black border around the background? It's really bugging me!

How do you make the background scroll? Because how my background looks right now is kinda ugly in my opinion~
