Adobe on Monday announced the first public preview release of its Edge HTML 5 Web motion and interaction design tool. This lets Web designers add animation to websites using standards such as HTML, JavaScript and CSS in much the same way they do with Flash Professional, Adobe said. It's adopting an open development methodology for Edge because of rapid changes around HTML 5. Edge is being positioned as complementary to Flash rather than its replacement. "Flash and HTML 5 products will continue to coexist," Adobe spokesperson Vanessa Rios told TechNewsWorld.
