HTML5 is the latest version of HTML, the markup language used to build structure or content on World Wide Web. HTML5 is the latest web standard by W3C. Earlier HTML was used only to build webpage structure, but HTML5 is a full on package to build websites, handle presentation, add functionalities and Web APIs.

HTML5 is the recommended version to build modern web applications as it is light and fastest version of Hypertext Mark up Language, the code that describes web pages. HTML5 was formed in 2009 and start supporting in browsers in 2010 onwards.

HTML5 Stack

Html5 is the combination of three web technologies:→

HTML → to build webpage structure,
CSS → to enhance look and feel( presentation layer), and
→ to add functionality to HTML elements.

The term HTML5 means not only HTML, it is a combination of HTML, CSS and Javascript with APIs. For example, drawing and animation using canvas, offline storage, microdata, audio and video, drag and drop, geolocation, embedded fonts, web APIs etc. HTML5 includes new semantic tags and some old tags( with redefinition ).



HTML5 has been designed to deliver almost everything you'd want to do on web without requiring additional software such as browser plugins. It does everything from animation to apps, music to movies, and can also be used to build complicated web applications that run in your browser.

HTML5 isn't proprietary, so you don't need to pay royalties to use it. It's also cross-platform, which means it doesn't care whether you're using a tablet or a smart phone, a net-book, notebook, ultra-book or a Smart TV if your browser supports HTML5, it should work flawlessly.

HTML5 Changed Elements

These elements were already there in HTML4/XHTML. But in HTML5, the definition or usage has been changed.

  1. a tag is now Hyperlink, not anchor
  2. a tag <a> can have both inline and block child elements.
  3. b tag is offset text conventionally styled in bold
  4. i tag is offset text conventionally styled in italic
  5. u tag is offset text conventionally styled with an underline
  6. cite tag is cited title of work
  7. hr tag is Thematic Break, not Horizontal Rule
  8. input tag is Input Control.
  9. meta tag is meta data.
  10. s tag is struck text.
  11. small tag is small print.
  12. dl tag is description list, not definition list.
