title: Moving back to parent frame in Selenium
body: <p>For moving back to parent frame in Selenium,
  <code>driver.switchTo().parentFrame();</code> is used. In my example website, I achieved same functionality using <code>driver.switchTo().defaultContent();</code> also.</p>
  
  <p>Is there any functional difference between these two:</p>
  
  <pre><code>- driver.switchTo().parentFrame();
  - driver.switchTo().defaultContent();
  </code></pre>
  
  <p>While referring to frames in a HTML document, are "Parent Frame" and "Default Content" different? Please explain.</p>
