Hi Pat,
Thanks for sharing the conversation. I tried to install JCE and saw that JCE supports to load specific template.css file or template_css.css file in a Joomla! template. This is quite not flexible as depend on each framework that a Joomla template is built with, not all styles will be put into template.css file. Like JA Blockk, in this case, the file 9.css is generated based on your configuration for template style with ID: 9 in Backend >> Extensions >> Templates
This file will load all styles that you configure in backend for this template style: Heading, Page settings, Font, and other styles. The default style uses Google font, of course, you can change to other font as you wish.
And JCE is not a default editor in Joomla so I think you can ask them for support if they can load more specific files instead of forcing to load 'template.css'.
Regards
