Its still possible to buy them from @gregpozo, for the ones who are interested.
I have bought them in January, even though his web is dead, which is a pity I need to say.
Also implemented as an HTML card. The codes are provided once you buy it.
Im using is as below for example, my “quotes” are too big so needed something a little bit different
Awesome. Thanks for sharing. I think I will sit down and improve my infobox snippet in the future to add some color and icons.
As a suggestion if I may: you could increase the radius size of your quote box, increase the paddings and remove the outline. I think this would match very good with the aesthetics of your website.
