True, but imagine

  foo       {color: #ABCDEF; background: #FEDCBA;}
  foo:hover {color: #FEDCBA; background: #ABCDEF;}
  bar       {border-color: #ABCDEF;} /* and so on */

or

  /* <quuz><bar/><foo/></quuz> */
  quuz, bar, foo {margin: 0; padding: 0;}
  bar {width: 200px;}
  foo {float: left; margin-left: 200px;}
