  <meta name="assert" content="This test checks how 'min-height' with calc(percentage) and 'box-sizing' are handled. The percentage in the calc() is calculated on the content box height of div#container.">

  <style>
  div#container
    {
      border-bottom: transparent solid 100px;
      border-right: transparent solid 100px;
      height: 400px;
      width: 100px;
    }

  div#item
    {
      background-color: red;
      box-sizing: border-box;
      height: 50px;
      min-height: calc(50% - 100px);
    }

  div#item > div
    {
      background-color: green;
      border-bottom: green solid 34px; /* arbitrary border-bottom-width value */
      border-top: green solid 12px; /* arbitrary border-top-width value */
      box-sizing: border-box;
      height: 17px;
      min-height: 100%; /* content height should be 100px - 34px - 12px == 54px */
      overflow-y: visible;
      /*
      If the content height of innermost div is taller
      than 54px, then a green rectangle (not a square)
      will be created.

      If the content height of innermost div is less
      than 54px, then an horizontal stripe of red
      will become visible.
      */
    }
  </style>

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