Here is the effect I'd like to recreate: http://www.fintechinnovators.com/
Notice when you hover over one of the companies, a grey-background div slides in from the left, covering the div you hovered over.
Inspecting those elements (divs), I see the grey div has a higher z-index, so it's able to cover up the original div.
Would I simply add a hover interaction to the first div and "affect a different element" (the grey div)?
I'm trying to understand how to achieve the slide in left-to-right effect. I see the grey-div is originally styled left:-100%. How do I get it to slide in?
