  Bug 137367: Implement orphans and widows
  https://bugzilla.mozilla.org/show_bug.cgi?id=137367

  -->

  <meta name="assert" content="This test checks that 'widows' applies to multi-column containers and that the initial value of 'widows' is '2'. When an UA succeeds at applying 'widows', then there is 2 line boxes at the top of the 3rd column box.">

  <style>
  div
    {
      border: orange solid 4px;
      font-size: 20px;
      line-height: 1.3; /* computes to 26px */
      height: 104px; /* Therefore, exactly 4 line boxes */
      margin-bottom: 1em;
      padding: 0.5em; /* computes to 10px */
      width: 460px;

      columns: 4 auto;

      column-fill: auto;

      column-gap: 1em; /* computes to 20px */

      column-rule: blue solid 4px;
    }

  div#test
    {
      orphans: 1;
      widows: initial;
    }

  div#reference
    {
      orphans: 1;
      widows: 1;
    }
  </style>

  <p>Test passes if the digits inside both orange-bordered rectangles are <strong>distributed identically</strong>.

  <div id="test">1<br>2<br>3<br>4<br>5<br>6<br>7<br>8<br>9</div>

  <div id="reference">1<br>2<br>3<br>4<br>5<br>6<br>7<br><br>8<br>9</div>

  <!--          Same as div#test except 1 extra br here   ^    -->
