What is a key attribute of heading format styles?

A key attribute of heading format styles is that they are typically bold, centered, and increased in size compared to body text. This formatting makes headings stand out, allowing readers to quickly identify sections and understand the structure of the document. By using larger font sizes and bolding, headings draw attention and provide a clear visual hierarchy, guiding the reader through the material effectively.

In contrast, smaller font sizes, italics, or colorful text do not fulfill the primary purpose of headings, which is to create emphasis and clarity within a document. Therefore, the characteristic of being bold, centered, and larger in size accurately describes why this format is utilized for headings.
