In looking at the attached screen shot from mytheme.libraries.yml, I see ‘base:’, ‘component’, ‘layout’, ‘theme’, and so on.
Do these designations represent/do anything in practice? Or is this just for organization of the libraries.yml file, or does this imply where/when these CSS files load? For example, form.css only loads when a form is present.
I can see this happening in modules, but in the theme.libraries file?
Also, why isn’t a ‘yml’ or ‘yaml’ tag available here? y
