Description Anton P 2012-01-08 19:33:19 UTC 
Reported by Simon Sapin.

The Computed Value line of the 'content' property defined in 12.2 (http://www.w3.org/TR/CSS2/generate.html#content) says:

  # On elements, always computes to 'normal'. On :before and
  # :after, if 'normal' is specified, computes to 'none'.
  # Otherwise, for URI values, the absolute URI; for attr()
  # values, the resulting string; for other keywords, as
  # specified.

This appears to omit the cases of the :first-line and :first-letter pseudo-elements.  This is a consequence of the spec's convention of using the word "elements" to mean "elements or pseudo-elements".  However, in this instance, the effect is jarring since treating :before and :after as if they were not covered by the first sentence fools the reader into thinking that no pseudo-element is covered by that sentence.
