title: Difference between iframe, embed and object elements
body: <p>HTML5 defines several embedded content elements, which, from a bird's-eye view, seem to be very similar to the point of being largely identical.</p>
  
  <p>What is the actual difference between <code>iframe</code>, <code>embed</code> and <code>object</code>?</p>
  
  <p>If I want to embed an HTML file from a third-party site, which of these elements could I use, and how would they differ?</p>
