Thinking only in the scope of a desktop website, I'm wondering about the discoverability of mouse hover functionality.
Allow me to contrive a scenario to explain my question: Let's say I'm designing a web page for a restaurant like the one below:
This UI is fairly basic with only four main card-style UI elements. Let's say also that, on mouse hover, I have the cards expand and show, say, nutrition facts below each image and description. Besides the nav bar, there's nothing that can be interacted with, and the hover target area is the entire card.
My question is this: Is hover functionality in desktop websites more discoverable on websites with very simple UIs?
(Please don't develop your answers directly for this example, but rather towards the concept itself: hover functionality in simple desktop UIs.)
