A style guide is a set of standards for writing and design that helps ensure consistency in communication. It provides rules for grammar, punctuation, formatting, and tone, making it easier for writers and designers to create clear and cohesive content. Common examples of style guides include the Chicago Manual of Style and APA Style. Organizations often develop their own style guides to reflect their brand identity and voice. These guides can cover everything from logo usage to color schemes, ensuring that all materials align with the organization's image. This consistency helps build trust and recognition among audiences.
