I was editing the wrong header.tpl file. The one I needed to be editing was within the node_modules path and in the specific theme. It works as you said @pichalite
can someone tell me why this code is not working, I am trying to change the background color of the nav bar

#red is not a color (just

With the original transparent color:
thank you, got it.
