Yes, thanks, I am sure it can be done. Pretty much all new WP themes come this way, and it's also included with many Joomla templates and flexbox builders like Yootheme and SP. Your code is very solid in that it always, always works. I think though there's a way to have a smoother transition with the aid of a script. I've seen the basics of how it works but need some help implementing it on a JA T3 website. I appreciate that you are taking an interest. We will be using this quite a bit going forward.
