To Format the page numbering for different sections, follow these steps. When you’re done, choose the Close Header and Footer, or double-click anywhere outside the header or footer area to close it. On the Home tab, choose Font, and change, for example, the font style and family, and font size and color.
You also can change the appearance of the page numbers. Then delete or format the first page number as you like.
If you just want to change or delete the first page number of a section, double-click to open the header or footer on that page, and in the Options group on the Design tab, click Different First Page.
