Orientation of the first item after ordering CSS

Question

See this code: http://codepen.io/muji/pen/XpEYzO

I need to target the first element after , it was sorted by the css "order" property and assigned it another CSS property.

Is there any jQuery or something that I can use to find the first element after sorting and then addClass or something else? Thanks so much for any help

.wrap {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
}
.featured {
  order: 1;
}
.normal {
  order: 2;
}
.wrap div {
  flex-basis: 50%;
  background: #ddd;
  border: 2px solid #000;
}

/*this is the part I need help with, as it should only apply to the first element AFTER applying the "order" attribute*/
.wrap div:first-of-type {
  flex-basis: 100%;
  background: #f00;
}

, @Nenad Vracar, order ( dom-)

$('.wrap').each(function() {
  var items = $(this).children(),
    minOrder = Infinity,
    details = items.map(function(i, el) {
      var order = +$(el).css('order');
      if (minOrder > order) minOrder = order;
      return {
        element: el,
        order: order
      };
    }).get(),
    firstElement = details.filter(function(item) {
      return item.order == minOrder;
    })[0];
  
  $(firstElement.element)
    .addClass('highlight')
    .siblings()
    .removeClass('highlight');
  
});

.wrap {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
}
.featured {
  order: 1;
}
.normal {
  order: 2;
}

CSS- " " ( , order ), , , script ( ).

, , , . , .:-) :

// A worker function to tell us the priority of an element (low number = high priority)
function getPriority($el) {
  return $el.hasClass("featured") ? 0 : $el.hasClass("normal") ? 1 : 2;
}
// For each .wrap container...
$(".wrap").each(function() {
  var $this = $(this);
  
  // Get an array of its child elements
  var a = $this.children().get();
  
  // Sort it, putting featured first, then normal, then any others
  a.sort(function(a, b) {
    return getPriority($(a)) - getPriority($(b));
  });
  
  // Append them to the parent, which moves them
  $this.append(a);
});

.wrap {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
}
.wrap div {
  flex-basis: 50%;
  background: #ddd;
  border: 2px solid #000;
}

/* Just make the first div the highlighted one */
.wrap div:first-of-type {
  flex-basis: 100%;
  background: #f00;
}
