A page break in a document looks like this:
To delete a page break you created, click the Show/Hide button. Clicking this button displays various non-printing characters—paragraph indications, spaces, tabs, etc.—that you may want to temporarily see while you’re working on your document.
Click Home > Show/Hide .
Double-click the page break to select it and press Delete.
Or click to the left of the page break and press Delete.
Note: You can delete only the page breaks that you’ve put into your documents; you can’t delete the page breaks that Word adds automatically at the end of each page. Read more about how to Add a page break.
