what name spacing to use for div id's and classes?

This is backwards. Javascript prefers underscores.

The most widely accepted, unofficial standard is to use underscores in IDs, and hyphens in class names.

Beyond that, the naming conventions are your own personal preference.

Isn't that clear? I prefer to name my classes and ids the same way and
never had a problem using javascript yet (caused by "-" or "_").
