Like any good system, typography provides a method to accomplish a task. A typographic system establishes hierarchy, meaning it helps us prioritize content based on individual elements and relationships between them. It also helps our readers easily scan chunks of information and understand what they’re looking at. When done right, a typographic system feels intuitive, like an unspoken set of instructions. Without any internal logic in place, our content may look like a monolithic block, essentially stranding readers in a dark room without so much as a match.Jason Santa Maria.
