title: Flex 1 full width column then two columns
body: <p>I want to have one full-width row/column then directly underneath I want 2 50% columns with inner padding.</p>
  
  <p>For some reason, my code is putting everything on one row?</p>
  
  <p>Here's the fiddle: <a href="http://jsfiddle.net/3ro546yk/" rel="nofollow noreferrer">http://jsfiddle.net/3ro546yk/</a></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.a {display: flex}
  .header {background: red;}
  .col {flex: 50%; background: yellow; justify-content: space-between;}
  
  // add inner padding on yellow columns</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="a"&gt;
    &lt;div class="header"&gt;header&lt;/div&gt;
    &lt;div class="col"&gt;col 1&lt;/div&gt;
    &lt;div class="col"&gt;col 2&lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Thanks</p>
