A wiki I am an admin of, the Barbie girls Wiki (where I do fanfictions), has code where supposedly there is a left and right column. However, the right column seems to have been put on the left column instead. Could you tell me ways to solve the issue so it doesn't happen in that form of manner? Also, when I do visual editing, it shows the templates that are put together when they are supposed to be separate.

Do I use CSSS to fix the issue?
