Hi! So I bought this bundle and have been working with the "Stacked" coding. I want the boxes to have that faded kind of look like in the preview, but can't figure out how to do it. I've looked through both the html and css coding and haven't found any notes for the code that might make those boxes look the way I want them to. Is there something I need to add, or am I just blind? 😭😭😭
