Description William Chen 2015-01-23 01:43:52 UTC 
According to the grammar (http://www.w3.org/TR/selectors/#grammar):

  /* Note that pseudo-elements are restricted to one per selector and */
  /* occur only in the last simple_selector_sequence. */

The ::content pseudo-element isn't meaningful when it's the last simple selector and it should be allowed to show up more than once per selector.
