The Super Mario Bros. Principle
The release of Super Mario Bros. brought us gameplay like we have never seen before. An experience that still holds up to this day. One of the reasons is the architecture of the game: It allows designers absolute freedom in creating levels without spending any thought on the implementation. Not caring about the technical details, but still design without limitations? Isn't that something we'd love for web development? See how we use CSS custom properties, web components and the power of the Cascade to transcend into creative Nirvana. Just like Miyamoto did 30 years ago.
