  • :target pseudo-class
  • New pseudo-classes: :enabled, :disabled, :checked, and :indeterminate
  • :root pseudo-class
  • New expression-based structural pseudo-classes: :nth-child(), :nth-last-child(), :nth-of-type(), :nth-last-of-type()
  • Other new structural pseudo-classes: :last-child, :first-of-type, :last-of-type, :only-child, :only-of-type, :empty
  • The negation pseudo-class :not()
  • Four pseudo-elements with double-colon syntax (::first-line, ::first-letter,::before, ::after)
  • The following-sibling combinator (p ~ img)
  • ::selection pseudo-class (removed from the spec, but everyone uses it)
