Is there a LIVE site/demo of this working?

Hi,

No sorry there is currently no demo however there are a few sites where it’s being used.
It’s in swedish but here’s one: https://www.swedenwaterresearch.se/projekt/

that looks great on that site. Could you give us the CSS code to make it look horizontal … that would be great for a newby ??

You can just check the CSS using the inspector in Chrome/firefox/safari ??
