I'm sure this is a silly question, but what does "Body" refer to in Arial(Body)? Is Body a variation of style "Arial" or is it a part of the document that contains the Body of the text?



Does anyone know wtf "Body" means and how it influences the document as opposed to plain Arial?

Arial(Body) refers to the font used in paragraphs. A theme may use different fonts for Titles, Subtitles, Headings, Body, etc. You're using a theme that has Arial assigned to the body of the document.
