What does a heading typically describe in a document?

A heading typically describes the content that follows it in a document. Headings serve as signposts, guiding readers through the text by indicating the main topics or sections that will be discussed. This organizational tool helps to enhance readability and allows users to quickly locate specific information within the document.

When a heading is properly structured, it provides context for the information that comes after it, allowing readers to anticipate the nature of the content. For example, a heading titled "Benefits of Regular Exercise" clearly signals that the subsequent text will discuss various advantages associated with exercising regularly. This practice is especially important in accessible documents, as it improves navigation, particularly for individuals using assistive technologies.

Other options relate to aspects of document creation but do not accurately represent the primary function of a heading. For instance, layout pertains to the overall arrangement of text and visuals on a page, whereas visual appeal focuses on aesthetic attributes rather than content organization or clarity. Lastly, a list of references is a separate component that serves to credit sources used in a document, and does not directly relate to the function of headings in signaling the content that follows them.
