the question does't make sense to me. Styling applies to the entire site.
If you setup your site and like it, you can export the settings (ato->export/import settings) and then import it into another site (it will replace any Atahualpa settings in the new site) and both sites will be styled the same way.
If you are talking about an individual page, you will have to copy the styling manually.
Give a person a solution, you fix one issue, teach a person how to solve their problem you enable them forever.
