Equal Width Link Tabs

1. Place the anchored links inside a "nav" div (here "sitenav")
2. Set the nav anchor display property at "display: block" so that you can give the link a fixed width (ems is probably best for this).
3. Then float the links inside the nav div so that they line up again in a row rather than stack vertically.
4. If necessary: Put a stretcher div inside the nav div so that it doesn't collapse once you float the links.
5. Center the nav div by setting margins to auto and giving it a fixed width.

Then play around with margins and padding to get it to look right with the rest of the page.
