10 reasons to use HTML5 (and one is accessibility)

En la página Codrops

they do a “countdown” of the 10 reasons to adopt HTML5 and accessibility is the first. Specifically it says:

HTML5 simplifies the creation of accessible pages for two main reasons: semantics and ARIA. New HTML headers (some already available) such as <header>, <footer>, <nav>, <section>, etc. they allow screen readers to access content more easily. Before screen readers had no way of determining what one was

determined or even if it had an assigned ID or class. With the new semantic tags, screen readers can better examine HTML documents by offering a better experience to their users.

The ARIA is a W3C specification used primarily to assign "roles" to elements in an HTML document - primarily by creating important landmarks on pages: header, footer, navigation, or article, via the attribute role. So far it has been ignored and infringed mainly because it was not valid but HTML5 already validates it. In addition, HTML5 will incorporate roles that can be overwritten making this role assignment trivial. For more detailed information on HTML5 and ARIA please visit the WAI.
