title: How can I align 2 first elements on the left and the last one on the right
body: <p>I think my code is in order, but I do not know why I am unable to organize my elements in this way:</p>
  
  <pre><code>|**   *|
  </code></pre>
  
  <p>This is my code:</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>.container {
    border: 1px solid red;
    display: flex;
    justify-content: flex-start;
    width: 100%;
    height: 200px;
    flex-direction: row;
  }
  
  .container div {
    border: 1px solid blue;
    height: 100px;
    width: 100px;
  }
  
  .right {
    display: flex;
    align-self: flex-end;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="container"&gt;
    &lt;div&gt;
      1
    &lt;/div&gt;
    &lt;div&gt;
      2
    &lt;/div&gt;
    &lt;div class="right"&gt;
      3
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>What am I doing wrong? This is my live code: <a href="https://jsfiddle.net/uxpkh9nL/" rel="noreferrer">https://jsfiddle.net/uxpkh9nL/</a></p>
