Ryan Stewart, Developer Evangelist Adobe and Scott Fegette, DreamweaverProduct Manger, show off some new tools in Flash and Dreamweaver CS5. Fegette’s run through consisted mostly of the new live preview built into the latest version of Dreamweaver giving the user, well, live previews of their content as they would appear in the browser. Not only that, it now has multi-screen previews built in, allowing the user to create profiles for mobile phones, tablets and PC based browsers based on width and height. You can then create css profiles that respond to these widths and load custom css files for each. He also gave a short preview of their browser labs project allowing you to view and test across multiple browsers and OS’, which can be found at browserlab.adobe.com. Here you can use the 1, 2 and 3 keys to switch between a 1-up, 2-up and 3-up onion skinned view to see how your pages flow will change across multiple browsers.
