I think that's ultimately what I mean. As an example, compare this screenshot of my site[0] with css and Javascript on to this screenshot[1] with it off. It's still perfectly usable, even if it doesn't look nice. But the same basic structure of the page is evident, and it's not like things are suddenly jammed together or messed up.
