  <meta content="invalid" name="flags">

  <!--

  <shadow> = <color>? && [<length>{2} <length [0,∞]>? <length>?] && inset?

  The box-shadow property attaches one or more drop-shadows to
  the box. The property accepts either the none value, which
  indicates no shadows, or a comma-separated list of shadows,
  ordered front to back.

  <style>
  div
    {
      background-color: red;
      box-shadow: green 100px 100px inset;
      /*
      This inset 'box-shadow' declaration will paint and cover
      the inside of the red square. This way, we verify that
      the UA actually supports 'box-shadow'.
      */
      box-shadow: none, red 0px -100px, red 100px 0px, red 0px 100px, red -100px 0px; /* invalid */
      box-shadow: red 0px -100px, none, red 100px 0px, red 0px 100px, red -100px 0px; /* invalid */
      box-shadow: red 0px -100px, red 100px 0px, none, red 0px 100px, red -100px 0px; /* invalid */
      box-shadow: red 0px -100px, red 100px 0px, red 0px 100px, none, red -100px 0px; /* invalid */
      box-shadow: red 0px -100px, red 100px 0px, red 0px 100px, red -100px 0px, none; /* invalid */
      height: 100px;
      width: 100px;
   }
  </style>

  <p>Test passes if there is a filled green square and <strong>no red</strong>.
