Because that way every instance of a first-level heading that needed the
desired effect would have to include the class attribute. When hand-coding,
especially, it's a waste, and the coder has to remember how to achieve the
effect. By establishing a division as a special area of the document,
contextual selection ensures that every <h1> in that division gets the
applied formatting. Other rules might set forth how to treat the entire
series of heading levels, or how to display dictionary lists (which I think
might work well for the "label : value" arrangement at the top of a
displayed post). None of those tags would have to be marked up to indicate
that they are treated differently, their mere presence inside the <div> of
that particular id attribute makes the difference. An <h1> inside a <div
id="pageheader"> would NOT get that particular style rule applied. Oops, and
that rule declaration should be #postheaders, sharp for id, dot for class.
Sorry. Someone coming along later adding a heading at that location needn't
even know that there is a style rule but it would get applied anyway.
Contextual selection, adjacent elements selection, first-child selection,
there is a whole array of tools to apply style rules to a particular element
while avoiding the placement of a class for a particular element.
