  <title>CSS Backgrounds Test: box-shadow in 3 sub-tests with inset and Npx 0px</title>

  <!--

  <shadow> = inset? && <length>{2,4} && <color>?

  A comma-separated pair of numbers in curly braces {A,B}
  indicates that the preceding type, word, or group occurs
  at least A and at most B times.

  A question mark (?) indicates that the preceding type,
  word, or group is optional (occurs zero or one times).

  The components of each <shadow> are interpreted as follows:

  1st <length>
    Specifies the horizontal offset
    of the shadow. A positive value draws a shadow that is offset to
    the right of the box, a negative length to the left.

  2nd <length>
    Specifies the vertical offset
    of the shadow. A positive value offsets the shadow down, a negative one up.

  4th <length>
    Specifies the spread distance.
    Positive values cause the shadow to expand in all directions
    by the specified radius.
    Negative values cause the shadow to contract.

      background-color: rgba(0, 0, 255, 0.5);  /* semi-transparent blue */
      border: black double 18px;
      height: 36px;
      margin-bottom: 36px;
      width: 36px;
    }
