CSS Day returns! This annual CSS community conference brings specifiers, implementors, teachers, and authors together to discuss the current state of CSS, upcoming features, and cool demos.
On 11th and 12th of June 2026 we'll run our twelfth edition with fourteen speakers. Ticket sales are open.

From our extensive correspondence with literally none of you we know that you all have pressing life questions such as "How many of my CSS heroes will I meet at CSS Day?" and "How many flamethrowers will they aim at me from stage?"
The answers are lots and probably none, respectively.
You trust us, right? I mean, we're very protective of our target audience.
