  <title>CSS Pseudo-Elements Test: inheritance of selection highlight colors from its parent element</title>

  <meta name="assert" content="In this test, 'color' and 'background-color' have not been given a value for the span element. Since its parent element has an highlight pseudo-element, then these values should be inherited. Therefore the span element should be green on a yellow background and should not use the OS default selection highlight color values.">

  <!--
  When any supported property is not given a value by the
  cascade, its value is determined by inheritance from the
  corresponding highlight pseudo-element of its originating
  element's parent element (regardless of whether that property
  is an inherited property).
