Basic usage
Number sections
Use counter-increment to advance a named counter on each matching element. The counter is usually created with counter-reset and displayed with content.
Overview
Introduce the document structure and goals.
Installation
Add the package and wire it into the build.
Configuration
Customize counters, selectors, and content output.
<article class="counter-reset:section"> <h2 class="counter-increment:section content:counter(section)::before inline-flex::before r:full::before">Overview</h2> <h2 class="counter-increment:section content:counter(section)::before inline-flex::before r:full::before">Installation</h2> <h2 class="counter-increment:section content:counter(section)::before inline-flex::before r:full::before">Configuration</h2></article>Count backward
Pass a negative integer to decrease a counter. Here the first generated value is 10 because the counter starts at 11 and decrements before it is displayed.
