Has anyone added a custom footer to Discourse?

Hi. I recently found the footers over at BootSnipp Bootstrap Footer Examples and wanted to use one of these in my own Discourse forum. Bootsnipp separates HTML, CSS, Javascript - so it is easy to cut’n paste that code into the Customize sections of my Discourse.

I tried several but each one does not center on my Discourse. I thought there might be a conflict among generic tag names (like “row” or “container” - so I tried adding “footer-” to the front, but that did not help.)

There seem to be at least 2 issues:

  1. the centering doesn’t seem to work
  2. the CSS columns effect also does not work.

Is there a setting I can change in my Discourse Settings area to allow these effects to happen in the footer? Should I be using certain tag names?

I hope to add links to websites related to my forum down there. I may also try adding a banner zone like I used to have in our pre-Discourse days.
