title: List with floating section headings
tags: visual,advanced
---

Creates a list with floating headings for each section.

- Use `overflow-y: auto` to allow the list container to overflow vertically.
- Use `display: grid` on the inner container (`dl`) to create a layout with two columns.
- Set headings (`dt`) to `grid-column: 1` and content (`dd`) to `grid-column: 2`
- Finally, apply `position: sticky` and `top: 0.5rem` to headings to create a floating effect.
