open web camp: css3 implementable features
DESCRIPTION
CSS3: You can use CSS3 selectors to target almost any item on the page without adding markup. Rounded corners, tilted images. Drop shadows. CSS3 is the latest and greatest and all the cool kids are doing it. But there is a lot of crazy syntax to memorize and what happens when all browsers are not capable of the effects you are after?In this session we will learn which CSS3 selectors and design features are supported in modern browsers, and tips and tricks for handling browsers that aren't quite there yet. Welcome to the next generation of web design!TRANSCRIPT
