Margin is the area between the edge of the page and the main printed area. Together, the four margins (top, bottom, left, and right) look like a rectangle around the page’s perimeter. Margins don’t print when you print or export the publication.

1. Click the Preferences button from the Crater Editor top bar.

2. Find the Show Margins option and toggle it on for showing them or toggle off if you wish to hide them.

3. Save the page and you are done!
