This is a introductory video about CSS3, what has changed fundamentally and semantically from previous versions of CSS. It comes from lynda .com one of my favorite resources for up-to-date information and tutorials for web design, programming, photography just about anything you want to learn.
Every tutorial I have watched from lynda.com is very thorough and concise, detailing every step of the process. I often watch these videos to refresh my self on topics before starting a new project. It helps to organized my thoughts and decide want I want out of a project.
As I said before this is an introductory video. I thought I should start at the beginning (or at least the beginning of the most recent version) of CSS.
Hope you enjoy and learn from it.
