CSS Day is the annual CSS community conference that brings specifiers, implementors, teachers, and authors together to discuss the current state of CSS, upcoming features, and cool demos.

On 3rd and 4th of June 2027 we'll run our thirteenth edition. Do you want to talk about CSS in real life, and not just online? Make friends, not followers? Then come. You'll love it.

Due to popular demand you can now buy 2027 tickets on the 2026 budget.

Subscribe to our newsletter to hear about the early-bird tickets first. Those will be on the 2027 budget, though.

The 2026 archive page, videos (on Conffab), photos and group photos have been published.
