Why CSS Sometimes Sucks

Can you predict with 100% confidence what will be the visual result of the following code?

CSS can be frustrating because it relies on rules and concepts we usually don’t learn and practice.
Not knowing those concepts makes CSS code unpredictable and it can annoy the hell out of anyone.

This website teaches you those concepts, allowing you to face any CSS issue with confidence. Straight to the point, information-packed katas (= exercises), will lay a strong theoretical base and put those new skills to practice with live code editors.
