Themes are used to support the content of a document, e.g., headlines, subheadlines, outlines, tables of contents. They are similar to headlines in that they are short summaries of the main ideas contained in the document. However, themes are less specific than headlines and can be longer than them on average (about two pages) compared to one page for the shorter headlines.1. Select Design then Themes options
