No padding on password page for password-protected pages

I have a site that uses Unicon with a Fullwidth layout style selected in the Theme Options.

I have two password protected pages on that site.

With the fullwidth layout selected, there is no left-hand padding between the edge of the browser window and the main content on the automatically generated password form.

Is there a way to adjust this, so that the password form is centered, for example, or by adding some padding?

Thanks,
SR
