Yep, IDs must be unique within a page, but classes do not have to be.
Apart from anything else IDs have to be unique because they serve more
purposes than just CSS: They are also used to make anchors, in
replacement of <a name=""/>, and are used in scripting to grab elements
using document.getElementById(); and having more than one of the same ID
will really screw you round when you're trying to work with this stuff.
