Brilliant. I have been doing a little bit of CSS over the years and I can get what I need done albeit not as quickly as some frontend developer that has every quirk of IE6 memorised. Since I generally do backend stuff sometimes I put in an extra class, e.g. for the end of a list, just 'to make it easier' on the CSS side of things. There are things like A+B that I steer clear from as they are allegedly bad according to tools like 'ySlow'. So I have plenty to learn when it comes to CSS selectors. Normally I look at the CSS and the HTML, not the big picture beyond 'inspect element'. I felt that CSS Diner is very useful even if you think you know your subject. The graphics are great. I wish all education was as much fun and as interactive. Like many folk here I did not understand what the game was at step #1 although I forgot this at step #2. So yes, some introduction needs to be worked on even though it is easy to overlook that once you get 'absorbed'. Aside from that, brilliant and bookmarked.
