View file within a style in new window?

clethrill

Let's say my vanilla forum theme is a white box surrounded by a blue background. Am I able to view the file with styling. So I can view it, say, centered with some padding, withing a white box and a blue background? or even the menu bar still at the top so then you can navigate back to the site? So it still has the feeling of the site.

I don't think this is even possible, and is way beyond my skills with any sort of scripting.
