Page Table of Contents
Turn a long page into a scannable set of anchored sections.
What it does
A generated list of a page's headings, with anchor links and an indicator for the section currently in view.
How it works
- 1 Generate the table from the headings actually rendered on the page. Do not maintain a hand-written list beside the content — it will drift.
- 2 Derive stable anchor ids from heading text, and disambiguate repeated headings deterministically so a shared link keeps pointing at the same section.
- 3 Offset every jump by the height of any sticky header, so the target heading is not hidden underneath it.
