HTML5 is being developed in joint collaboration of the Web Hypertext Application Technology Working Group (WHATWG) and World Wide Web Consortium (W3C). As the development of HTML5 are still going on so it is not yet an official standard. No web browser supports all HTML5 elements yet, but popular web browsers like Firefox, Chrome, Internet Explorer, Safari, Opera etc. are adding more HTML5 tags support in their latest versions.
For example, we have given below a small HTML5 code snippet for creating a simple web page:
<!DOCTYPE html> <html> <head> <title>Your first HTML5 page title</title> </head> <body> Your first HTML5 page </body> </html>
