The move is necessitated by the overall lack of support for Google's WebM video codec, which Mozilla and Google hoped would replace H.264, the technology backed by Apple, Microsoft, Nokia and other commercial vendors. Mozilla's war on H.264 has gone on for nearly three years, but now the company's leading developers have admitted, "we lost. " HTML5 Rocks - A resource for open web HTML5 developers. HTML5.

HTML5 in the browser: Local data storage. Of all the changes bundled in the HTML5 drafts, few are as radical or subversive as the options for storing data locally.

HTML5 in the browser: Local data storage

From the very beginning, the Web browser was intended to be a client in the purest sense of the word. It would display information it downloaded from a distant server, and it would do everything the distant server would tell it to do. Programmers discovered the limitations to this fairly soon, and before long browsers started offering website developers the chance to leave a little piece of data behind. The creators tried giving this 4,096-byte text string a cute name, "cookie," but that didn't stop the controversy.

HTML5 in the Web browser: HTML5 forms

All of the hard work that went into building self-checking widgets and the libraries that ensure the data is of the correct format is now being poured into the browser itself. The libraries won't be necessary -- in theory -- because the work will be done seamlessly by all browsers that follow the standard. In practice, we'll probably continue to use small libraries that smooth over slight inconsistencies.

The new HTML specifications include input types that offer a number of new options for requesting just the right amount of data -- say, a form element that requests the time in different levels of granularity, such as month, week, or minute.
