Lately I have been testing out performance among css styles and I found that some of my very smart friends, started asking,”why aren’t you testing using IDs for the unique sections of the page?”.

This wasn’t a hard answer:

1. The element is not re-usable on that page.
2. This is the begining of a downward sprial into specificity
3. Usually, IDs refer to something very specific, and abstracting would be tough
4. Any performance gains picked up by using id, is negated by adding any other selector to the left fo that id
