If that is the case for you, follow the accepted use for your organization. These headings are usually centered and each letter can be capitalized. Headings of the first rank should be displayed in the largest type. The typeface may be different from the type used for the text, but it should be compatible with the text's typeface. Rank A second-rank heading starts three or four lines below the previous section, flush with the left margin and on a line by itself.
Important words begin with a capital.
The size should be smaller than first-degree headings, but larger than the text type. Headings of the Third Rank A third-rank heading is usually indented on a line by itself and is a line below the preceding text. Third-degree headings may be the same size as the text, but they are usually darker or of a different type face so that they cannot be easily confused with the text. Headings of the fourth rank usually form the first words of a paragraph. If they refer to material covered in more than one paragraph, they may be set off from the text with a period.
