This document discusses formatting documents in Microsoft Word using styles and themes rather than direct formatting. It explains that styles allow formatting to be applied consistently throughout a document and that if the style needs to be changed, only that style needs to be modified rather than changing formatting individually. Themes are also discussed, which determine the styles used and can change the look of the entire document at once by modifying existing styles or adopting a new theme. The document emphasizes that styles, rather than direct formatting, should always be used for documents.
