title: List with sticky section headings
|
|
tags: visual,intermediate
|

|
|
|
|
Creates a list with sticky headings for each section.
|
|
|
|
- Use `overflow-y: auto` to allow the list container (`<dl>`) to overflow vertically.
|
|
- Set headings (`<dt>`) `position` to `sticky` and apply `top: 0` to stick to the top of the container.
