I agree. It seems that's why there are templates for other articles of this series. The inconsistencies in Firefox are due to inconsistencies what Browsers do with 'gray' (or 'grey'?) instead of rgb hex values, imho. That could be solved if we set border="0" on the tables or use hex values. Problem is: If hex, which one? I think the CSS article looks great in this respect, we should copy the style (so no border).
