In an classroom setting, I wouldn't recommend it...or any of the Head First series for that matter. They are all essentially hands on self-paced tutorials, not text books or references.

The big advantage is that they model improvement in their exercises by using sample code that is half-right (and half-wrong) and then showing how to improve it.

All that to say that they aren't for everyone, and certainly are not targeted at people who prefer reference manuals. On the other hand, the exercises in Head First HTML really demonstrate how CSS formatting works (and doesn't work) better than other beginner level books.
