Suppose we only want to modify Heading 2. For example, let’s say we want to center, bold, and italicize it. The quickest way to do this would be to change the selected style, then right-click on that style in the “Styles” section on the “Home” tab, in this case Heading 2, and select “Update Heading 2 to Match Selection.”
Highlight a header in the text, then open the Paragraph dialog box (right click the paragraph and choose Paragraph from menu).
In the Indents and Spacing tab, change Outline level to proper number.
