my five-page odt file shows all five pages. I only want the last page.

How can I get the file with only one page at a time on the screen, so I can edit it?
The pages are purple and too small to read. I want the text to be black, with only one page at a time on the screen, so I can continue writing to it. Thanks, Don B.
