Workshop Details

Used to their full extent, CSS custom properties can facilitate better collaboration and code reuse, improve maintainability, and downright enable possibilities that previously required large amounts of hard-to-maintain JavaScript and violated separation of concerns. They truly are a revolution in the way we write CSS!

Is This Workshop for Me?


This workshop is for everyone who writes CSS, or JS that interacts with CSS. This includes front-end designers, front-end and full stack developers. It will be especially useful for anyone who writes code that is used by other developers. And not that this is an advanced course and not an introduction.

Any Prerequisites?

  • A solid understanding of CSS
  • A basic understanding of JS (mainly events and basic DOM)
  • Basic familiarity with CSS Custom Properties is helpful, but not required
