How to make a HTML5 document

Hypertext Markup Language

You Have to know: 

HTML5 is a markup language utilized for organizing and introducing content on the World Wide Web. It is the fifth and current version of the HTML standard.

New tags have come with HTML5 :

Lots of new syntactic highlights are added. To locally incorporate and handle media and graphical substance, the new <video>, <audio> and <canvas> components were included, and bolster for adaptable vector illustrations (SVG) substance and MathML for scientific recipes. To enhance the semantic substance of reports, new page structure components, for example, <main>, <section>, <article>, <header>, <footer>, <aside>, <nav> and <figure>, are included. New traits are presented, a few components and qualities have been expelled, and others, for example, <a>, <cite> and <menu> have been changed, reclassified or institutionalized.

Basic Structure of HTML5:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Document title</title>
</head>
<body>
Content
</body>
</html>
