Adobe Systems today announced it's public preview release of Adobe® Edge, a new HTML5 web motion and interaction design tool that allows web designers to bring animation, similar to that created in Flash® Professional, to websites using standards likes HTML, JavaScript and CSS. Because of rapid changes around HTML5.

This tool will enable all web developers who love to create web content with motion and transitions. Adobe Edge is being designed as a fast and lightweight professional-grade tool that complements Adobe's existing Web tools, such as Adobe Dreamweaver® CS5.5, Adobe Flash Professional CS5.5 and Adobe Flash Builder® 4.5 software.
According to Adobe, the software enables users to add motion to existing HTML documents without hampering design integrity of CSS-based layouts, and it also enables users to easily create visually rich content from scratch, using familiar drawing tools that produce HTML elements styled with CSS3. Users can import standard Web graphics assets such as SVG, PNG, JPG and GIF files and style them using CSS3.
The design stage utilizes WebKit to enable design, preview and manipulation of content with incredible fidelity. The innovative timeline feature is both familiar for creative professionals and breaks new ground in animation productivity to enable users to define and customize motion applied to HTML elements with extreme precision. Content created with Edge is designed to work on modern browsers including those on Android, BlackBerry Playbook™, iOS , HP webOS and other smartphone mobile devices as well as Firefox™, Google Chrome™, Safari™ and Internet Explorer 9™.
