Was there ever resolution to this? I, too, am struggling with putting something like this together. The trouble with the summary sections is they require you to link that information to somewhere else on your site. I just want 3 rectangular floating cards that highlight information about the product or service on the page.
I used rectangle shapes with drop shadow and added text over the rectangles, but on certain browsers everything appears awful, honestly. Even the screen shot that I've attached looked better on my ginormous display than it does right now on my laptop. And don't get me started about how it appears on mobile at the moment 😄
Would love any ideas on how to create something like this without summarizing a different page somewhere else on the site, since this is to just highlight certain aspects of what they're looking at on the page they're on.
Thanks!
