title: flexbox justify-self: flex-end not working?
body: <p>I have a layout where <em>sometimes</em> the 'left' item is missing. In such cases, I still want the 'right' item to be right-aligned.</p>
  
  <p>I thought I could do this with <code>justify-self</code> but that doesn't appear to be the case.</p>
  
  <p>Is there a flexbox property for right-aligning one's self?</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>.row {
    border: 1px solid black;
    display: flex;
    justify-content: space-between;
    align-items: center;
  }
  
  .left,
  .right {
    display: inline-block;
    background-color: yellow;
  }
  
  .right {
    justify-self: flex-end;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="row"&gt;
    &lt;!--&lt;div class="left"&gt;left&lt;/div&gt;--&gt;
    &lt;div class="right"&gt;right&lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
