Need help understanding what must be transferred to a Child Theme. I have modified my Twenty-Twelve theme only in two ways:
1. Using the Appearance-Customize section - changing simple things like background image, header image, sidebar hierarchy, etc.
2. Added Function PHP code to convert my old BlogSpot to WordPress
Now I want to install a Child Theme. Please advise what I need to toss into the Child Theme. The basic Appearance changes? The Function PHP?
