Even for a Computer Engineer w/ 30 yrs experience (but no real .css knowledge), I found the tutorial (and experimenting) to provide excellent quick access. For me a picture is a thousand words.

I haven't finished the course yet (my first time trying to learn OOP) but it is very clearly presented, very interesting, and I am finding it helpful. I am sure I may have to watch the videos more than once, but that is just me.

I have previously looked at some of the free videos from Killesites, and they are all very good.

Love mini courses!
