HTML 5 Tag Reference
HTML 5
HTML 5 improves interoperability and reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors.Some of the new features in HTML 5 are functions for embedding audio, video, graphics, client-side data storage, and interactive documents.
HTML 5 also contains new elements like <nav>, <header>, <footer>, and <figure>.
The HTML 5 working group includes AOL, Apple, Google, IBM, Microsoft, Mozilla, Nokia, Opera, and many hundreds
of other vendors.
Note: HTML 5 is not a W3C recommendation yet!
