HTML 5 Fast and Now Beautiful
HTML5 is a markup language used for structuring and presenting content for the World Wide Web and a core technology of the Internet. It is the fifth revision of the HTML standard.
In particular, HTML5 adds many new syntactic features. These include the new video, audio and canvas elements, as well as the integration of scalable vector graphics (SVG) content (that replaces the uses of generic object tags) and MathML for mathematical formulas. These features are designed to make it easy to include and handle multimedia and graphical content on the web without having to resort to proprietary plugins and APIs.It is also an attempt to define a single markup language that can be written in either HTML or XHTML syntax. It includes detailed processing models to encourage more interoperable implementations; it extends, improves and rationalises the markup available for documents, and introduces markup and application programming interfaces (APIs) for complex web applications.Many features of HTML5 have been built with the consideration of being able to run on low-powered devices such as smartphones and tablets.
It is crucial to remember that HTML5 is built on the success of its previous version, HTML 4.01, which is undoubtedly the best version ever. In order to be better at using HTML5 you do not need to forget everything about the previous version. You are not learning a totally new language here. Keep your beloved syntaxes and keep the way you used to format your code, only remember that now you need to build upon the coding skills you already have.
In case you have absolutely no knowledge of HTML and you want to start now, I advise you to start with HTML 4.01 and only when you master it move onto HTML5. Starting with the latest version is like learning to run before learning to walk – which is impossible as far as I know. HTML 4.01 still contains the basics of HTML5, therefore in my opinion you should have strong knowledge of former HTML versions in order to be able to master HTML5.
