1, insert delimiter. Delimiters are especially useful for arranging headers and footers in different formats. The function of separator is equivalent to dividing the whole word into different independent parts, making the whole part into many sections, so as to design the formats of different parts independently.

2. Before editing the header and footer, it is best to separate each section. After dividing the festival, double-click the title to edit it.

3. There is no header or footer on the cover, so you don't need to edit it (this is the first section). Place the cursor at the header of the summary page (this is the second section) and click "Link to the previous section header" in the toolbar, so that the format of this section can be edited independently, instead of following the same section as the first section.
