Wouldn't it be cool to be able to use CSS3 and HTML5 unfettered by the lack of support in IE? Mobile developers for smart phones get to do just that!When developing for iPhones, iPods, iPads and Android devices—mobile devices using webkit browsers—we can use CSS animations, transforms, multiple background images, rounded corners, text and box shadows, CSS columns, and HTML5 form elements.In this session we'll use some CSS3 features learned in earlier session to create a native looking iPhone web app. We'll also cover some CSS UI and HTML5 form elements that will help you get up to speed on developing for mobile webkit. You don't have to wait any longer to use CSS3!
