Title: Migrating CSS from Flex 3 to Flex 4
Tags: apache-flex;flex4;flex3;flex-spark;halo
Question: Is there a guide or document that deals specifically with migrating CSS and style attributes from Flex 3 to Flex 4? I have an application that I'm keeping on the 2006 namespace, but I'm having trouble with a couple concepts, like the halo only styles, the CSS namespacing conventions, and styling child controls.


Here is the accepted answer: Here is a good start, you'll need to scroll down to the CSS part.
