I forgot where I put my CSS. yep, I'll admit it.
In Chrome DevTools, I am use to seeing the CSS source file. I get that Moodle caches so, outside of Designer mode it just shows 'all'.
I'm in designer mode and can find the CSS I so brilliantly created but, all I can figure out for the source file is "http://moodle.saintsimon.site/theme/styles_debug.php?theme=fordson&type=scss"
I found it by searching the server for scss files but would still be nice to know.
