Design guidelines are a set of principles and best practices that are used to guide the design of user interfaces. These guidelines provide a framework for content editors to follow in order to create consistent and effective designs

Design guidelines are based on research, user feedback, and industry standards, and are intended to help content editors create pages that are both aesthetically pleasing and easy to use. They can cover a range of design elements, such as layout, typography, colour, imagery, and interaction design.

Design guidelines are important because they help to create a consistent and cohesive design language, which in turn helps to build trust and familiarity with users.
