Go through the database and create a file that PurgeCSS can read with Sage 10. Default location is theme/resources/views/vendor/purgecss-with-sage/classes.blade.php. Configuration of output location is not available at this time.
# /web/app/themes/sage
$ composer require tylerwiegand/purgecss-with-sage
# web/app/themes/sage
wp acorn purgecss-with-sage
I'd also personally recommend a .gitignore addition of the generated file in Sage's .gitignore file:
# web/app/themes/sage/.gitignore
/resources/views/vendor/purgecss-with-sage/classes.blade.php
As of 1.1 it will also search the cssClass set in a GravityForm field if the plugin is active.
