How do I align my items to always place it on top. I am using flex to my container.
Note: The number of items are dynamically generated.
<div class="container">
  <div class="item">ITEM 1</div>
  <div class="item second">ITEM 2</div>
  <div class="item">ITEM 3</div>
</div>
.container {
    display: flex;
    flex-wrap: wrap;
    flex-direction: row;
 }
 .item {
     width: 45%;
     height: 100px;
     background-color: lightgray;
     margin: 0 20px 20px 0;
     display: flex;
     justify-content: center;
     align-items: center;
 }
 .second {
     height: 150px;
 }
Here is my plunkr
