I'll describe what I'm trying to do and perhaps someone can help, if they have an idea. I have a fixed navbar with a high z-index, so always on top. I have a fixed hero image, low z-index, always on bottom. I have sections with z-index between the two. I wanted to be able to click on the navbar categories and have those sections scroll up to the top of the page using in-page linking (thus covering over that hero image. That seems to work.
But what do settings do I use (and possibly class styles) to be able to click on the Home button, and have all sections scroll back down, thus revealing the hero image, as when the page was first loaded?
