What is HTML5?

My super-short post that attempts to answer this question as completely and accurately as possible in three presentation-friendly bullet points.


  • re-imagines HTML as an API ~~with objects, events, interfaces, and methods~~ or a collection of interfaces.
  • defines an algorithm for generating a consistent, cross-browser friendly DOM tree, regardless of the quality of the author's markup.
  • adds new elements with semantic meaning and multimedia capabilities.
