Simple header, footer

My JS and CSS are a bit rusty. I tried using vix but it seems so complicated.

I just want something simple to get my V0 out. Simplicity will be better. Are there other places I can use this from?

On a related note, I see many website having "copyright 2018-" etc etc. See e.g. firecalc.com. What does copyright mean? Do I need to include it?
