From Web Dev Studios: A style guide can typically encompass a company’s branding guidelines, which could include: logo usage, designated color palettes, and editorial tone. It is often wrapped in to a deliverable for, or by a company to work with outside vendors. Style guides often fundamentally aid in establishing a company’s internal baseline for product and service goals, and exhibit a cohesive customer experience. Style guides can directly influence the look and feel of a pattern library. Style guides can stand on their own without data, while pattern libraries rely on some data to function.
