When adding headings, what is a recommended practice?

Adding headings effectively is crucial for enhancing the readability and organization of a document. The practice of inserting one additional line of space above your heading serves several purposes. It visually distinguishes the heading from the text that precedes it, making it more noticeable and creating a clear separation that guides the reader through the document. This added space helps to group related content together without overwhelming the reader, allowing them to easily navigate the structure of the document.

In terms of other strategies for headings, while catchy phrasing might attract attention, it may not always be appropriate depending on the context or purpose of the document. Similarly, making each higher-level heading yield at least three lower-level headings could lead to unnecessary complexity or clutter if the content does not support that structure. Lastly, limiting to only two levels of headings might not provide enough differentiation in a document that requires a more detailed hierarchy. Therefore, introducing an additional line of space is a universally beneficial practice that supports clarity and organization in technical communication.
