No changes here, correct?

Including any changes outside of changes material to the issue at-hand makes PR review more challenging, risky, and comes with longer merge times. If you're able to remove these changes, that would be helpful.

The CSS was conflicting and not given priority , so I moved it down to ensure it applies correctly @leecalcote
