How to use the transitions feature to make element fade in on hover?

I’ve been trying to use the Transitions feature to make an element fade in on hover.
Perhaps you can see why it’s not working:

hmm it should work. Make sure the title container is set to opacity 0 when hidden, and opacity 100 when shown (don’t toggle visibility). And set the transition on the title container as well.

Setting the titleBox visibility to 0% istead of hidden/not-rendered did the trick.
Thank you!
