^{Originally posted by cruxcode November 7, 2022} Some CSS properties must be applied to all the elements on the page. Examples, of such CSS properties, are background, typography etc. Sometimes users may want to have some default value already applied for these properties for a head start in a project.

The proposal is to import some resources like fonts, and icon fonts by default in a project. The user can remove it if needed.
