CSS changes when users scroll past section

  • Hi!

    Is there a way for the menu CSS to change when a user scrolls past a given section?

    To be clear, let’s say I’ve a sidebar menu like:
    1. AAA
    2. BBB
    C. CCC

    When I’m reading the 2. AAA section of the post, for instance the sidebar link “1. AAA” would be greyed out, and the sidebar link “2. BBB” would be highlighted. This would be dynamically updated as I scroll up and down, so just looking at the sidebar would let you know which section you are currently reading.

    Is there such an option or tweak?
