I am creating a fanon wiki for the Minecraft Series "Songs of War". I'm a beginner to source code, so I know how to use wikitext and make basic backgrounds for pages. I have attempted a few times to add a right column on my wiki, but I have not been successful.

The left column works, however.

Does anyone know how to fix this?
