title: Responsive css tiles stack in pyramid shape
body: <p>I have a row of 3 inline-blocks the span the width of the page horizontally:</p>
  
  <p><img src="https://i.stack.imgur.com/XYZfp.png" alt="enter image description here"></p>
  
  <p>When the page reaches 1000px wide I want the tiles to stack themselves as a pyramid:</p>
  
  <p><img src="https://i.stack.imgur.com/Zbwhw.png" alt="enter image description here"></p>
  
  <p>And then at 460px they need to stack vertically:</p>

  <p>My current html/css structure is:</p>
  
  <pre><code>&lt;div class='tile-row'&gt;
      &lt;div class='tile'&gt;&lt;/div&gt;
      &lt;div class='tile'&gt;&lt;/div&gt;
      &lt;div class='tile'&gt;&lt;/div&gt;
  &lt;/div&gt;
  
  .tile-row{
      margin: 0 auto;
      max-width:1485px;
  }
  
  .tile{
      width:32%;
      display: inline-block;
      height: 200px;
  }
  </code></pre>
  
  <p>How would I set up media queries to accomplish the above scenarios? Is there an easier way to do this without using media queries?</p>
