With the introduction of Flex 4's Spark architecture, Flex component skinning has never been easier. With this new skinning approach, the art of CSS styling components appears to have been left in the shadows of Flex development. Many of the Flex 4 version of components no longer provide the same level of CSS support as their Halo equivalent. However, Flex 4 has not abandoned CSS styling and it has even been enhanced with the Flex 4 SDK to allow for new ways to provide styling for components. In this session, we will walk through the CSS features of Flex, what is new with Flex 4, and how we can take advantage of CSS to help provide robust styling support for our components and more specifically our skins. Let's rediscover Flex styling together!
