HTML5 IS THE NEW FLASH

摘要

The big advantage of standards is that you don't get locked in. If you don't like what a browser (or photo-viewer, or whatever) does, just download a different one and use that instead. On the other hand, using a proprietary format restricts which software you can use. And if you want to change, you have to convert all your documents. The key term for describing the original web (and I would claim, its success) is the word 'declarative'. A declarative definition describes what you want, rather than how to get it. Declarative definitions are typically short and easy to understand.
