A guide to CSS units — pt. 1: look at these absolute units!
Four part series on units in CSS, where we dive into each available unit, explain the relationship between them and try to find out when to use which. We will talk about accessibility, best practices for developer teams and the history of sizing stuff on screens (and in print). This first part will present a general primer on the topic of size units, teach you everything you need to know about pixels and prepare you for the rabbit hole we are about to go down.
