HTML5 is backed by the big software companies: Google, Microsoft, Apple, Mozilla, IBM, HP, and more. HTML5 is where the internet is going.
Screen readers can view website content much easier with the new HTML5 semantic tags. No more Flash! Media is accessible by screen viewers without the heavy coding necessary to get your media to play correctly.
HTML5 comes with powerful tags enabling simple embedding of videos, music, and other media like animations. A few lines of HTML5 code are now suffcient, the integration of Flex, Flash, or Silverlight no longer required.
