Foundation 6 theme, using Top Bar. I can’t adjust the background colour nor can I set the height of the bar. Previous answers from 2016 show fields no longer there in the setup for the Top Bar.
Thanks… that sorted the colour, but does padding affect the total height of the bar or where it is on the page?
Padding adds additional height to the bar - dependent on the size of the menu font, which of course also defines the height in some way.
The positioning could be done with a margin-swatch or a position-swatch.
