1. If you want to set separate headers and footers for the page, you need to divide the page into separate parts. First, position the cursor before the first character of the current page, switch to the page layout ribbon, click the separator drop-down menu, and then select section break-Next Section.

2. Then position the cursor after the last character of the current page. Similarly, click the "Separator" drop-down menu and select "section break"-"Next Section".

3. Next, you can modify the contents of the header or footer of this page independently: double-click the corresponding header or footer to enter the editing state, and at the same time, in the Header and Footer tool panel, click Cancel Link to Previous Header. As shown in the figure:

4. At the same time, enter the editing status of the next page "Header or Footer" and click Cancel "Link to the previous page header".

5. After completing the above settings, you can set the contents of the header or footer in this separate page. As shown in the figure, I found that the headers of other pages did not change when I entered the content.

6. In addition, there is another situation, that is, when we want to set different pages to the same page number, or input regular content, we can use the "field" function to achieve it. First, enter the header or footer editing state, switch to the Insert ribbon, and click File Part-Domain Code Item.

7. In the opened domain window, select the corresponding domain code according to actual needs, select the "Page" domain in this small series, and click the "OK" button.

8. At this point, you will find that the page number has been successfully inserted into each page. Of course, all subsequent pages have been successfully applied except the independent page and the previous page previously set.
