What is the main purpose of using "Styles" in a document?

Using "Styles" in a document primarily serves to maintain a uniform look for text and headings. Styles allow users to apply predefined formatting settings such as font type, size, color, and paragraph spacing to similar sections of a document consistently. This ensures that headings, subheadings, and body text have a cohesive appearance, which not only contributes to the document's aesthetic appeal but also improves readability and organization.

When styles are applied, any changes made to a style automatically update all text associated with that style throughout the document. This feature saves time and effort, especially in lengthy documents, as it allows for easy adjustments while retaining a professional and polished look. Furthermore, using styles can enhance the functionality of the document by making it easier to create a table of contents or navigate through sections, as many word processing programs include these features linked to styles.

In contrast, the other options focus on distinct functionalities that do not relate directly to the primary purpose of styles. For instance, saving documents in different formats pertains to file management, tracking changes involves version control and collaboration features, and managing embedded multimedia content addresses the incorporation of visual and audio elements, none of which align with the core function of styles in document formatting.
