Type size and style. This book, which is a long and complex document, uses various levels of headings. These levels of headings are distinguished by type sizes and fonts as well as by color.

In a college paper, you will usually distinguish levels of headings using only type—for example, all capitals for the first-level headings, capitals and lowercase boldface for the second level, capitals and lowercase italics for the third level, and so on.
