Yes, Emacs supports a limited form of "rich text". See text-mode. It's supported by text properties [1] and overlays [2]. Character properties are special attributes attached to a single character, while overlays can attach attributes to a "region" and override old text properties (like div in HTML). In Emacs, > A button is essentially a set of text or overlay properties, attached to a stretch of text in a buffer. [3] The Emacs display engine is sorta like an HTML render engine.
