I started with restarter and the official restarter child theme from github.
I purchased restarter plus and it says that it does not support the child theme so I had to revert to the vanilla restarter theme just to use the restarter plus plugin.
Thankfully I had not yet modified the child theme, but it is my intention, ie to change colours.
1. Is restarter plus going to support restarter child theme?
2. Do I need child theme to change colours? ie purple banner. I see there is custom css available, but I am new to wp so not really sure what this offers me - is there any beginners documentation - I do know CSS, just not how it integrates with wp.
