Default Margins Padding

Does anyone have a list of all the CSS Classes that Elementor uses for default Margins and Padding.
I create all my pages with the Elementor Canvas template, and would like it to be a clean, clear of any default Margins or Padding. Basically, a true blank page.
My big issue – when I ever uncheck the linked margin or padding, all of the margins or padding default to the pre-set values. The Margin and Padding boxes do not show the default values, so never sure how things will change, and where or what elements in the chain will be effected.
Currently, my work process is to uncheck the linked Margins and Paddings for every Section, Column, and Element added. Would hope that adding CSS to clear all pre-set default Margins and Paddings will save me from unchecking every time.
Issue also comes up with Section Templates, as the templates added to a page, as a global section, get added with linked Margins and Paddings, and need to be unlinked for the global section to look like as saved.
