An ID lookup is the fastest you can get to access an element. In
browsers where getElementsByClassName has been implemented finding by
class is also quite fast, but not as much, by ID is definitely faster.
In your example, $("p.para") would be faster if you don't require that
it's a descendant of a div. From jQuery 1.3 you have to think of
selectors from right to left.
