@zkamvar We need to update style for this lesson so that jump lists (anchors for different sections) becomes automatically available for different levels of headings.

Hello @annajiat. I'm no @zkamvar editor, but it looks like the sections and levels are linked. We will close this as completed, but feel free to reopen it by giving an example. Thanks!
