List of Web Safe Fonts?

[Black Max]

To my eye, Corbel works well as a wide sans, much like Verdana, while Candara has enough "flair" in its design to work in a situation where you'd normally use Trebuchet.

Not sure I agree with the font stack for the site you link:

candara, tahoma, geneva, sans-serif;

But you're right, the site looks nice in Candara.
