    <title>CSS Test: Testing min-height:auto & 'overflow' interaction</title>
    <link rel="author" title="Daniel Holbert" href="mailto:dholbert@mozilla.com">
    <link rel="help" href="http://www.w3.org/TR/css-flexbox-1/#min-size-auto">

<!--
     This testcase checks how "overflow-x" indirectly impacts the sizing
     behavior of flex items with "min-height:auto" (the new initial value
     for "min-height"), via its influence on "overflow-y".

     In particular, the flex-item-specific "min-height:auto" behavior is
     supposed to be disabled (e.g. we end up with min-height:0) when
     "overflow-y" is non-"visible".  Moreover, when "overflow-x" is set to a
     scrolling value, it forces "overflow-y" to compute to a scrolling value
     as well, as described at
       http://www.w3.org/TR/css-overflow-3/#overflow-properties
     So, "overflow-x" has an indirect effect (via "overflow-y") here.

      .flexbox {
        display: flex;
        flex-direction: column;
        height: 30px;  /* Shrink flex items below min-height */
        margin-right: 2px; /* (Just for spacing things out, visually) */
        float: left;
      }

      .flexbox > * {
        /* Flex items have purple border: */
        border: 2px dotted purple;
      }

      .flexbox > * > * {
        /* Flex items' contents are gray & fixed-size: */
        background: gray;
        width: 40px;
        height: 80px;
      }

      .xvisible { overflow-x: visible; }
      .xhidden  { overflow-x: hidden;  }
      .xscroll  { overflow-x: scroll;  }
      .xauto    { overflow-x: auto;    }
    </style>

  <body>
    <!-- min-height:auto should prevent shrinking below intrinsic height when
         the flex item has "overflow-x: visible", but not for any other
         overflow-x values (because of overflow-x's influence on overflow-y).
