Yup, HTML 6 and CSS4 announced today. All major browsers agree to fully support on day one.
While we wait for HTML5 and CSS3 to be finalized and deal with the sluggish support in all major browsers, the WWW Consortium has announced the new versions. They also mention that all major browsers are to support the features and render the same on all devices and promise no more hacks or the need to target browsers specifically. It was also noted that all major browsers would do a “force upgrade” of all browsers in use today. W3 said that the plan to eradicate old browsers still in use today involved a 2 year discussion with all major the browsers (IE, Fire Fox, Safari, Chrome, Etc…) on the best approach. What was decided was to simply render the old browsers useless and force the user to upgrade.
