With this code, you should be able to have a separate background for each category page on any layout! It goes on the bottom.
Change the direct links in the parenthesis for different backgrounds. You can get direct links for new images by logging into an Imgur account, uploading the images, and then go to Images on the upper right (click on your username) and click on your image: https://i.imgur.com/sPeZ6kF.png. As an alternative, you can use Postimages.org for a direct link.
/*CURRENTLY WATCHING WALLPAPER
To change background images: Delete what's in the parenthesis. Upload the new background to Imgur or a similar site, then copy the direct link (or Original GIF link if it's animated) and paste it into the parenthesis. Save.

Change the background by the tag
In the example pic, I clicked the "shonen" tag on an anime, and the background changes to a special background for this tag. You can make custom backgrounds for a tag with this code, just change "Shonen" with your own tag.
