A style guide is a comprehensive document that outlines the specific guidelines and standards for creating and maintaining consistent branding, design, and content across various platforms and channels. It serves as a reference tool for writers, designers, and marketers to ensure that all communication materials align with the brand’s identity, tone, voice, and visual elements. A style guide typically includes instructions on grammar, punctuation, formatting, typography, color palette, logo usage, and other essential elements that contribute to a cohesive and recognizable brand image.
