OK, it was my functions.php file. I was not loading the parent theme correctly. SOLVED!
So my child theme seems to be the problem, and I cannot figure out why. Using the actual Sparkling theme works fine. I activate my child theme and nothing scales down when the browser viewport size is reduced. At full viewport size, the theme displays properly. I cleaned out all css modifications from my child theme and it still doesn’t work. It is something on my end and not a theme problem. I will bang on things until I get it to work as I do like the theme.
No link as this is on my local host (wamp server). The images do not scale down like they should, and it might be something to do with WAMP, but I have never had this problem with other responsive themes I have tested and used. I will play with it more and see if I can find a solution.
