[ZeroGravity]
In the mean time I have chosen the theme ZeroGravity and created a minimal child theme as described in Child Themes. Just minimal, doing nothing other than the original. I am going through the code and doing some reading. Would appreciate any guidance.
I am a newby to WordPress, have a basic idea of HTML, CSS and PHP, experienced in the Unix CLI. The site is running in my own virtual server.
