From highest priority to lowest priority.
User important style sheets
Author important style sheets
Author normal style sheets
User normal style sheets

User agent style sheets
It is pretty clear in this article: http://www.quora.com/In-what-order-do-CSS-definitions-take-priority
CSS declarations are applied in this order (from lowest to highest priority):
· User agent declarations (the default styles your browser applies to elements)
· User normal declarations (a user’s own stylesheet if they’re using one)
· Author normal declarations (this is your normal stylesheet)
· Author important declarations (anything your mark important)
· User important declarations (any important styles from the user’s stylesheet)
