As an addendum to the earlier post about css resetting, here’s another version from Yahoo though it’s far less user friendly:

YUI Reset CSS

The foundational YUI Reset CSS file removes and neutralizes the inconsistent default styling of HTML elements, creating a level playing field across A-grade browsers and providing a sound foundation upon which you can explicitly declare your intentions.

Note: YUI Base CSS (introduced in version 2.3.0) can compliment Reset by applying a style foundation for common HTML elements that is consistent across A-grade browsers.
