HTML 5 Introduction:

  • HTML5 is the latest and most enhanced version of HTML.
  • HTML is not a programming language, but rather a markup language.
  • HTML 5  is the advanced version of HTML 4.01, XHTML 1.0, and XHTML 1.1 and has superseded all  these versions.

HTML 5 Features:

  • The DOCTYPE declaration for HTML5
  • <!DOCTYPE html>
  • The character encoding (charset) declaration is also very simple:
  • <meta charset=”UTF-8″>
  • HTML 5 removes extra information required and you can use simply following syntax −
  • <script src = “scriptfile.js”></script>
  • The type attribute is already removed from elements.
  • Like from <link type=“text/css” > the type is removed from stylesheet.

  • New semantic elementslike <header>, <footer>, <article>, and <section>.
  • New attributes of form elementslike number, date, time, calendar, and range.
  • New graphic elements: <svg> and <canvas>.
