Hi  @Aaron S ,

welcome to the Atlassian community!

You can edit footer and footer at space level and not for a single page or a subset of pages within you space. 

In order to edit header and footer in every page in every space (if you are a Confluence admin) by going to the global Settings , then in the Look and Feel section of the left-hand menu select Page Layout.

Hope this helps,

Fabio
