If you want to use a different format, contact your instructor. Avoid pronoun reference to headings. Don't use headings as lead-ins to lists or as figure titles. Keep at least two lines of body text with the heading, or force it to start the newt page. In this guide and in this course, you use a specific style and format for headings.
Most organizations expect their documents to look a certain way.
Pay close attention to formatting details such as vertical and horizontal spacing, capitalization, use of bold, italics, or underlining, and punctuation. Notice that you can substitute bold for underlining. Use Roman numerals with first-levels. Underline or bold the words but not the Roman numeral. Make first-levels centered on the page.
