I posted this as a comment on the YouTube video about this, but it doesn’t look like you monitor those…
Basically, when I create anchor links to the section heading as shown, when you click a link, it takes that to the top of the browser window, so if you have a header on the page it completely covers much of the section you’re trying to read. In the olden days we would have placed a transparent pixel where we wanted the anchor, but I don’t know if there’s a simpler solution or not.
