You could think of it that way. But if one can be used many times and the
other only once, I wouldn't say that they are almost identical. =) Classes
are internal names for "classes" or "types" of elements. An ID is a name for
a particular element.

If you think about it in a certain way, classes actually have more in common
with element names (i.e. P, H1, DL) than with IDs in that they describe a
certain kind of data, whereas IDs name a particular data element.
