If you're considering whether a project should be open-source or not, I hope you'll find it valuable.

In this post, we'll explore a technique we can use to "fold" a DOM node, like folding a letter in real-life. On that journey, we'll learn a lot about 3D transforms and CSS animation techniques!

CSS variables are *really* cool, and they're incredibly powerful when it comes to React! This tutorial shows how we can use them with React to create dynamic themes. We'll see how to get the most out of CSS-in-JS tools like styled-components, and how our mental frame around media queries has been wrong all along.
