Page-specific css rules - where to put them?

Question

Often when I\'m designing a site, I have a need for a specific style to apply to a specific element on a page and I\'m absolutely certain it will only ever apply to that element

Answer 1

Put it in the place you would look if you wanted to know where the style was defined.

For me, that's exactly the same place as I would place styles that were used 2 times, 5 times, or 170 times - I see no reason to exclude styles from the main stylesheet(s) based on number of uses.
