I have a page that will have a lot of text for the reader. To help the reader get an overview and navigate the page, I would like to have a menu in my sidebar with the different anchors as menu-items. I want the menu to be “sticky” and for the current anchor in the menu to have a certain background color. In regards to sidebar objects being “sticky”, please note that I also have sticky navigation, so there must be some sort of margin-top so that the sidebar widget isn’t covered by the sticky navigation.
