title: Cross Browser support for CSS Flexbox
body: <p>I have been using the code mentioned below, it works on my Chrome but not on my IE9 and Safari.</p>
  
  <p>I googled for the solution, despite I got various vendor prefixes, those results are baffling me.</p>
  
  <pre><code>&lt;div style="display: flex; flex-direction: row;"&gt;
      &lt;div&gt;&lt;/div&gt;
      &lt;div&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
