Yet another child theme topic-not showing changes

I am very new to this, and just trying to experiment with some changes to see what I like, but nothing seems to follow through to the main site.

I have looked through the forum as much as I could and ran through what topics I found (Special thanks to the code posted on the Customizr site for searching the forum works great :)) so far I have not found a fix.

I have tried various “snippets” with no success. Below is the code that I have been modifying. Since it is nothing special I am assuming that it might be an easy fix. Thanks for the help.
