Since the publishing of its First Public Working Draft in 2008, HTML5 (not HTML 5) has gained wider acceptance among developers and designers.

How to Start Using HTML5
So what do you need to do to start using HTML5? At the very least, you can change your DocType Declaration from the more complex HTML 4 version
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
or to add more HTML5 markups
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Page Title</title> ... </head>
That’s all there is to do to start using HTML5. So even if you haven’t been able to update all your markup, there shouldn’t be any reason for you not to switch to HTML5 now.
