I'm joined by Dustin Schau in this video and he is going to take me on a tour of the world of what has come to be known as CSS-in-JS. That is, doing your styling entirely in JavaScript, rather than in .css files that you link up in the head all on your own.
Dustin is a perfect guide for this, as he created a great exploratory tool called CSS in JS Playground and also has a brand new course on the subject.
