title: FlexBox - How to display one column 100% and two others 50%
body: <p>Looking at the bellow code, I'm trying to have the 3 child columns as follow:</p>
  <p>The first column should be 100% wide and above two other columns.
  Two other columns should be bellow the first column and each 50% wide.</p>
  <p>Like this:

  <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>.flex-container {
      width: 80%;
      min-height: 300px;
      margin: 0 auto;
      display: flex;
  }
  
  .flex-container .column {
      padding: 10px;
      background: #dbdfe5;
      flex: 1;
  }
  
  .column.first {
      background: blueviolet;
  }
  
  .column.third {
      background: #b4bac0;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="flex-container"&gt;
    &lt;div class="column first"&gt;Column 1&lt;/div&gt;
    &lt;div class="column second"&gt;Column 2&lt;/div&gt;
    &lt;div class="column third"&gt;Column 3&lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>But whatever I try it doesn't work that way.</p>
  <p>Is it possible or I'm trying an impossible layout?</p>
