How to Remove the Space Between a Header in a Word Document

1. Place the cursor at the end of the header in the document.
2. Click 'File' from the top menu and then select 'Page Setup.'
3. Select the 'Margins' tab from the Page Setup properties window.
4. Decrease the 'Top Margin' value in the Margins properties. Decreasing the top margin value will move the text farther up the page, removing any space in between the document text and header.
5. Click 'OK' to set the margins.
