I want to create an app-like footer that is sticky and shows a navigation menu. Since I already have a “normal” footer which shows at the end of the content, I figured the best way to do this is to create a bottom bar in the PRO header builder. Everything works fine, but I’d like that bottom bar to be hidden initially and to show up when scrolling down a certain amount of pixels – just like the top bar header behaves. Unfortunately, such options are missing in the bottom bar builder.
By inspecting the top header bar I noticed that it initially has CSS declarations of position: absolute, visibility: hidden, and opacity: 0. When scrolling down, the position declaration changes to position: fixed and the element loses the other two declarations, which creates the appearance effect.
I guess there’s some jQuery code involved for this. How can I create the same effect for a bottom header bar using custom JS code in the header builder?
