You’ll see the row of three containers at the bottom, which I want to be clickable. To start out, I tried your suggestions on “CONSULTING”. I added the CSS you suggested, set the container block to clickable-container and added a link in the headline block within.
The headline is clickable, but not the parent container.
FYI, the site was in Divi – now removed – and I am rewriting it using GP & GB.
