I like to treat class and id semantically -- or at least according to
my understanding of what that means.
ID is properly used on elements (div, etc) that are unique.
Class is used with elements that are categorical or a "class" in the
mathematical and programming sense.
For me an ID is something like header, footer, masthead, basically
anything that makes sense as unique.
If I happen to have a page for which I currently only have one
newsitem. I will still use class. Simply because to me a page could
naturally have more than one newsitem. I don't base the notion of ID
simply on the fact of there being only one element of that type
currently. I base it on "there should rightfully be only one."
This is how I go about it. As they say "your mileage may vary."
