What is New in HTML5?
The DOCTYPE declaration for HTML5 is known to be very simple:
<!DOCTYPE html>
The character encoding (charset) declaration also seems to be very simple:
<meta
charset="UTF-8">
HTML5 Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
</head>
<body>
Content of the document......
</body>
</html>
The default character encoding present in HTML5 is UTF-8.
