I’ve triple checked and I’m puzzled at the moment. On the linked demo page, the effect work, in 3D. On my webflow test, it’s flat. I even created a totally blank webflow site with only this http://testflip2.webflow.com/ and have the same result. I’ve created a simple HTML file to test it outside of webflow, and still, the flip effect is flat, no real 3D.
So I’m left with that…
