Eeek there are so many to learn!
Guilty of using px, but in my defence i have only been learning for a month haha.
I had no idea % was called 'relative'. I came across it when using bootstrap.
There are quite a few here, so i am going to try to use one new unit each week to see if it sinks in.
Would love to see more articles of this ilk! I really enjoy your writing style and the Gifs help me to follow along :D
