If you, like me just get the CSS file done by the designer and wants to learn more, this website is pretty good.
There are videos very well done, Jeffrey way (the instructor) is very didactic.
It seems pretty basic, but for me I’ll finally learn how to create a proper css file! At least hope so, I’m still on day 3!
