8,605 PointsWhy are we using px instead of % for min-height/max-height, padding, etc?
I'm not sure if my question makes sense but aren't px a fixed number. Wouldn't it make more sense to make all these values "relative" by using %?

Long(er) answer: each has specific use cases and it is important to know when to use one over the other. I think px is an easier concept to teach to a beginner, which is why I'm sure Treehouse chose to start with this. There are too many specific/advanced cases where one might be preferable to the other, which I'm sure will become apparent with more experience.

However, what if you just wanted to add some padding to make a button for a link? It might be more appropriate there to add some pixels of padding and avoid interacting with the size of the container...
