title: What is the difference between HTML tags and elements?
body: <p>I notice that most people use the words <em>HTML tags</em> and <em>HTML elements</em> interchangeably. </p>
  
  <p>But what is the difference between them? </p>
  
  <p>The way I see it is that tags are in the source code and elements are processed tags (by the browser) in the DOM. Am I wrong?</p>
