Padding with glkote and Quixe interpreter

When releasing with an interpreter on Inform 7, you can delete the div containing the lefthand sidebar and the div for the Quixe credits (putting the credits somewhere else in the game, of course). This makes the text fill the whole screen.

It also looks ugly. I would like it to look more like cactus blue motel, where there is a uniform black border or padding or margin or something around the text. How can I achieve this with the standard Quixe interpreter?

I use this layout sometimes: … /play.html

See the “Header and footer” section on this page:

Thank you, this is exactly what I needed.
