Can't believe Ive never noticed this before. Maybe I forgot it. Either way its surprising to me. I feed my pre rules like this. #code pre. The code id on the body. I went to override the pre and put in some rules in the head a the doc like pre {...} without the id. Surprising to me it did not override it unless I included the id before hand. I would of thought the head trumped the id. Wrong obviously.

On a side note I am going to try only classes with my next project and no ids and see how it goes. I bet head would trump .class element {...}.
