CSS Courses
Our online courses on CSS, which generally take up a few half days, give you the same experience and access to experts that you would have in an in-person CSS workshop.

With our online CSS courses however, you can do it from your own desk or couch, and can do it either live (real-time) or watch the video course at your own leisure, as all video recordings are included.
Practical and interactive courses
Our online courses have a lot of practical examples and interactive exercises. If you are watching live, you can ask questions during Q&A, and of course you can use the online course recordings and materials to study CSS at your own pace, at your own time.
Courses on various CSS topics
We offer many online CSS courses at various levels, covering a wide range of CSS topics, such as Dynamic CSS, CSS Grid, CSS for Design Systems and many more. Please check our upcoming (live) courses, and see what CSS courses we have offered in the past, if be notified of new live offerings.
Blown away by all the knowledge I've soaked in from @rachelandrew's online CSS layout masterclass. Incredible how much you can learn about a thing you thought you already knew just by hearing it explained again. Thanks for organising this @smashingconf #smashingconf ✨

Cascading Style Systems: Resilient & Maintainable CSS
with Miriam Suzanne
Workshop, 5×2h + Q&A • Tue, Wed, Thu, June 2–10 2026
09:00 – 11:30 AM PT • 18:00 – 20:30 CEST • Check your time zone ⏰
New CSS features are shipping at an unprecedented rate – cascade layers, container queries, the ‘:has()’ selector, subgrid, nesting, and so much more.
It’s an exciting time, but the list can also feel overwhelming. Do I really need grids if I already know flexbox? What problem do layers actually solve? Should I rewrite my styles with each feature release, or stick with the tools that I know? It’s a good time to step back and understand how these tools fit together in a declarative system — a resilient cascade of styles. -

To build an accessible website, we need to understand HTML well. But once our designs and patterns get more complex and dynamic, being good at HTML is not enough. We need practical knowledge about UX, ARIA, assistive technology, and testing tools.
In this workshop, Manuel Matuzović will teach you how to build and test complex accessible components like accordions, modals, tabs, cards, and tables. -

“Oh, and by the way, the site has to be accessible!” — Wait! What? How? What does accessible even mean? Semantic HTML, right? Is there more? How do I test accessibility? Do I need special hard- or software? Are there tools I can use? How do I discover and fix accessibility bugs? How do I assure my site stays accessible? Can I automate testing? …
So many daunting and overwhelming questions, if you don’t know how to get started. Manuel Matuzović guides you through the first steps and takes a deep dive into automated and manual accessibility testing.
