title: What's the best way to achieve this layout with flexbox?
body: <p>I have 4 columns and three rows. The last tile is two rows high.<a href="https://i.stack.imgur.com/YNMah.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YNMah.png" alt="enter image description here"></a> </p>
  
  <p>I'm working on a code that looks like this:</p>
  
  <pre><code>.gridContainer {
   display: flex;
   flex-wrap: wrap;
  }
  
  .gridItems {
   width: 290px;
   height: 350px;
   margin: 0 5px 10px;
   border-radius: 4px;
  }
  
  .gridItemsTall {
    width: 290px;
    height: 710px;
    margin: 0 5px 10px;
    border-radius: 4px;
  }
  </code></pre>
