CSS Counters
Discover how to employ CSS integer variables to automatically number your headings and elements.
Table of Contents
CSS Counters are effectively “internal variables” preserved exclusively by CSS layout algorithms. You can increment or decrement them dynamically, enabling your style architecture to autonomously append numerical markings to paragraphs, headings, or list items without writing tedious JavaScript loops.
Initiating a Counter
To utilize this feature, the counter must initially be born. You create one at the root element of your choice using counter-reset. Subsequently, counter-increment nudges the variable skyward.
Nesting Counters
This technique gets profoundly powerful when building legally-bound hierarchical contracts or sub-chapters, where counters reset whenever a new primary class emerges.
