CSS lists and counters

The CSS lists and counters module enables styling and positioning of list item bullets and manipulating their values with a combination of strings, counters, and other features.

A list item's marker, whether a bullet symbol or ordinal counter, is its defining feature. List items are not limited to {{HTMLElement("li")}} elements nested within {{HTMLElement("ol")}} or {{HTMLElement("ul")}} elements. Rather, list items are any element with display: list-item set.

This module defines CSS features to set and reset a list's counters, set which counter-styles or symbols to use as its markers, and position those markers. It also provides developers with the ability to create customized markers.
