I am having trouble setting up a floating anchor menu that, as you scroll, flips through the links to show the active year that the page is currently at. For example, if I scroll down the page to the year 1998, 1998 is white in the nav menu until I scroll to the next or previous year, in which case that next link turns white and the other turns back to blue. Somehow, this is kind of happening, but with a color I didn’t even set. If you look closely, the color changes by just a few shades of blue.
The page in question is called “Past Concerts”.
