If you’ve been thinking that HTML5 is completely different from other flavors of HTML, you may be surprised to discover that the only required difference is the doctype line that appears at the very top of the file.
Here’s an example of a very simple HTML5 page.
<title>This is a simple page title</title>
<p>The content for a simple page goes here.</p>
Of course, there’s more to it if you want to create more complicated HTML5 documents. Most of the new HTML5 tags are designed to better describe the content and are intended to replace some of the <div> tags. For example, there is now a tag for <header> and another called <footer> reflecting the fact that so many websites include <div> tags with class or ID styles named footer and header
