CSS Class Collector (useful for CSS purging)
The CSS Class Collector module automatically scans your Drupal site
and collects all CSS classes used in database-driven content.
It generates a reliable, real-world list of CSS classes actually used across the site.
This is especially useful for projects using PurgeCSS,
Tailwind CSS, Bootstrap, or any CSS optimization
workflow that depends on accurate safelists to prevent removal of dynamic or
backend-generated classes.
By using this module, you can safely purge unused CSS without breaking layouts
or functionality.
